Police officers and SWAT team members greet each other after a police assault on a house in Watertown, Mass., Friday. The manhunt for Dzhokhar Tsarnaev, 19, one of two brothers believed to have carried out the Boston Marathon bombing ended with his capture while hiding in the stern of a boat parked in the backyard of a house.
WATERTOWN, Mass. — Police captured a19-year-old man on Friday night suspected of carrying out the Boston Marathon bombings with his older brother after a day-long manhunt using helicopters and heavily armed officers in a Boston suburb.
The Boston Police Department said on Twitter that the suspect was in custody and officers were sweeping the area.
Authorities identified him earlier as Dzhokhar Tsarnaev, 19, one of two brothers believed to have carried out Monday’s attack at the world-famous event, killing three people and injuring 176.
Police cars and armored vehicles surrounded a house in Watertown on Friday night shortly after police told a news conference that the suspect fled on foot and was still on the loose.
The apparent break in the investigation came after an intense manhunt that virtually closed the city of Boston.
Monday’s bombing on the finish line of the marathon was described by President Barack Obama as “an act of terrorism.” It was the worst such attack on U.S. soil since the plane hijackings of Sept. 11, 2001.
Images showed that the three-story house where Dzhokhar Tsarnaev was caught had a tarp-covered boat parked on a trailer in the backyard.
Earlier on Friday, Colonel Timothy Alben told a news conference that officers went door-to-door in Watertown and searched houses.
During the search for the men on Friday, two Black Hawk helicopters circled the area. SWAT teams moved through in formation, leaving an officer behind to ensure that searched homes remained secure, a law enforcement official said.
Details emerged on Friday about the brothers, including their origins in the predominantly Muslim regions of Russia’s Caucasus, which have experienced two decades of violence since the fall of the Soviet Union.
The fugitive described himself on a social network as a minority from a region that includes Chechnya, Dagestan and Ingushetia.
A man who told reporters he was an uncle of the brothers said they came to the United States in the early 2000s and settled in the Cambridge, Massachusetts, area.
Ruslan Tsarni, who lives in suburban Washington and said he had not spoken to the brothers since 2009, called the bombings “put a shame on our family. It put a shame on the entire Chechen ethnicity.”
In separate interviews, the parents of the Tsarnaev brothers said they believed their sons were incapable of carrying out the bombings. Others remembered the brothers as friendly and respectful youths who never stood out or caused alarm.
“Somebody clearly framed them. I don’t know who exactly framed them, but they did. They framed them. And they were so cowardly that they shot the boy dead,” father Anzor Tsarnaev said in an interview with Reuters in Dagestan’s provincial capital, Makhachkala, clasping his head in despair.
The FBI said the twin blasts were caused by bombs in pressure cookers and carried in backpacks that were left near the marathon finish line as thousands of spectators gathered.
The mother, Zubeidat Tsaraeva, speaking in English, told CNN: “It’s impossible, impossible, for both of them to do such things, so I am really, really, really telling that this is a setup.”
BOSTON — Police killed one suspect in the Boston Marathon bombing during a shootout and were engaged in a house-to-house search for a second man on Friday in the Boston suburb of Watertown after a bloody night of shooting and explosions in the city's streets.
Authorities warned people in Watertown not to leave their homes and not to answer the door. During the night a university police officer was killed, a transit police officer was wounded, and the suspects carjacked a vehicle before leading police on a chase that ended with one suspect shot dead.
Police said the suspect they were seeking was the man shown wearing a white cap in surveillance pictures released on Thursday night which had been taken shortly before Monday's explosions that killed three people and wounded 176 at the finish of the Boston Marathon. He has been identified as Dzhokhar A. Tsarnaev.
The blasts triggered security scares across the United States and evoked memories of the Sept. 11, 2001 attacks. On Friday the authorities effectively closed down Boston, halting transportation systems and telling people to stay home as the hunt continued.
Boston Transit Service Suspended Amid Hunt For Bombing Suspect
Boston police said on Friday that all transit service by the Massachusetts Bay Transportation Authority "has been suspended until further notice" as a manhunt for a suspect in the bombing of the Boston Marathon was ongoing in a city suburb.
Vehicle traffic was also suspended in and out of Watertown, Boston police said.
Officials said as police had closed in on the two men overnight they attacked the officers with explosives and gunfire before one of them, identified as Tamerlan Tsarnaev was shot and taken to a hospital, where he died.
"We believe this to be a terrorist," said Boston Police Commissioner Ed Davis of the suspect still at large. "We believe this to be a man who has come here to kill people. We need to get him in custody."
The dramatic events overnight followed the release on Thursday by the U.S. Federal Bureau of Investigation (FBI) of pictures and video of two suspects seen wearing backpacks and baseball caps in the crowd minutes before the bombs exploded.
FAA Closes Airspace Over Boston Manhunt Area
The Federal Aviation Administration closed airspace over a 7-mile-wide (11 km) stretch of the northwest Boston area on Friday to provide a "safe environment for law-enforcement activities" as police searched for a second Boston Marathon bomb suspect.
The restriction, which echoes similar measures imposed after Monday's bombing, applies to all aircraft flying below 3,000 feet (914 metres), according to an FAA bulletin.
There were no immediate reports of restrictions at Boston's Logan airport.
About five hours later, a university police officer was shot and killed on the campus of the Massachusetts Institute of Technology, the Middlesex County District Attorney said in a statement.
A short time later, police received reports of a carjacking by two men who kept their victim inside the car for about half an hour before releasing him, the statement said.
Police pursued that car to Watertown, where explosives were thrown from the car at police and shots were exchanged, the statement said.
"During the exchange of the gunfire, we believe that one of the suspects was struck and ultimately taken into custody. A second suspect was able to flee from that car and there is an active search going on at this point in time," Colonel Timothy Alben, superintendent of the Massachusetts State Police, told a news conference.
The wounded suspect was taken to Beth Israel Deaconess Medical Center, where he died, said Dr. Richard Wolfe, chief of emergency medicine.
"This was a trauma arrest, multiple injuries, probably, we believe, a combination of blast, potentially gunshot wounds," Wolfe told a news conference. When asked how many gunshot wounds, he said: "Unable to count."
The blast injuries may have been caused by "an explosive device, possibly shrapnel, thermal injury. It was pretty much throughout the trunk. It was multiple wounds," he said.
Inside the 20-block search area, police performed street-by-street checks of yards with full tactical gear, long rifles and full armor, a Reuters photographer witnessed.
Massachusetts Governor Deval Patrick suspended all public transportation service on the Boston-area subway, bus and rail system as a precaution.
"People that are at subway stations or at bus stops we are asking them to go home, we do not want people congregating and waiting for the system to come back on," said Kurt Schwartz, director of the Massachusetts Emergency Management Agency.
Schwartz also asked people in the Boston-area communities of Newton, Waltham, Belmont, Cambridge and the Allston-Brighton to stay indoors and asked businesses in those areas to remain closed pending further notice.
MIT said it canceled all classes on Friday after one of its police officers was killed.
U.S. President Barack Obama was briefed overnight by a counterterrorism aide on the Boston bombing investigation and manhunt, a White House official said.
