Police have the second suspect in the Boston Marathon bombing in custody after a stand-off in a Watertown backyard.

Elsewhere tonight, three people have been taken into custody in New Bedford as part of the terror investigation.

Watertown residents, just after the day-long "shelter in place" order had been lifted, were again asked to stay indoors as shots were fired in the area. A resident reported a guy had crawled under a boat and police and SWAT officers moved in on the location. About a dozen shots were fired in the vicinity.

Investigators spent much of Friday searching for the second suspect in Watertown following a chaotic night that left the first suspect dead. The Associated Press is reporting the surviving Boston bomb suspect is identified as Dzhokhar A. Tsarnaev, 19, of Cambridge.

"We believe this man to be a terrorist," Boston Police Commissioner Ed Davis said at a post-4 a.m. press conference about the at large suspect.

"We believe this to be a man who's come here to kill people. We need to get him in custody."

An MBTA Transit Police Officer was shot during the overnight manhunt through Cambridge and Watertown. Richard (Dic) H. Donohue Jr., 33, is in surgery now at Mt. Auburn Hospital, according to a police spokesman just after 8 a.m.The suspect is considered armed and dangerous.

6:20 p.m. Boston Marathon bombing suspect Dzhokhar Tsarnaev remains on the loose, but Gov. Deval Patrick has lifted the stay indoors order for all Boston area residents.

"The stay indoors request is lifted," Patrick said. "The T is open effective immediately. We are asking the public to remain vigilant if you are out. To that extent we can return to living our lives, that request is lifted, but remain vigilant.

"We are where we were effectively as of Monday night or Tuesday morning, with a couple exceptions," he added. "One of the suspects is dead. There was a firefight out here last night, with some 200 rounds and explosives, so we were very justified, I believe, based on what we understood about the investigation, in taking what we knew was a big step in asking people to stay indoors."

State Police Col. Timothy Alben said he believes Dzhokhar Tsarnaev is still in Massachusetts, and that he is the only person police are looking for at this time.

"We do not have an apprehension of our suspect this afternoon, but we will have one," he said. "We're committed to that."

Alben said police went through 20 streets in Watertown on Friday, door-to-door, doing limited searches to make sure everyone was safe. Police also followed a number of leads to "various places in Eastern Massachusetts," none of which have been fruitful to this point.

He said there is much left to be done, including ballistics and forensic work. He said exploded and unexploded ordinances were found at the scene.

"We are going to draw back our tactical teams, but state police will be providing additional patrols to Watertown for the next two to three days," Alben said.

"Unfortunately, we don't have a positive result at this point, but for the sake of everyone that was hurt or killed during the marathon or those police officers that lost their life or were seriously injured, we are committed to seeing a conclusion to this case."

Alben said the suspect is "a very violent and dangerous person," and said anyone who sees him or has further information about the case should call 911 or report any tips to the FBI's tip department.
