UPDATE/WATERTOWN, Mass. (AP) - Boston Police say a 19-year-old college student wanted in the Boston Marathon bombings is in custody after a manhunt that left the city virtually paralyzed and his older brother and accomplice dead.
Police announced via Twitter that Dzhokhar Tsarnaev was in custody. His brother, 26-year-old Tamerlan, was killed Friday in a furious attempt to escape police.
The brothers are suspects in Monday's marathon bombings, which killed three people and wounded more than 180 others. The men are also suspected of killing a Massachusetts Institute of Technology police officer in his vehicle late Thursday.
Authorities in Boston had suspended all mass transit and warned close to 1 million people in the entire city and some of its suburbs to stay indoors as the hunt for the remaining suspect went on.
WATERTOWN, Mass. (AP) - A law enforcement official says the suspect being hunted in the Boston Marathon bombing is in a boat stored in a Watertown, Mass., neighborhood.
The official said he was briefed on the situation and spoke on condition of anonymity because he's not authorized to discuss it publicly.
The official does not know if Dzhokhar Tsarnaev is dead or alive.
Authorities are telling residents of the area to stay indoors.
The burst of activity came at the end of a tense day in and around Boston, and less than an hour after police announced that they were scaling back the hunt because they had come up empty-handed following an all-day search that sent thousands of SWAT team officers into the streets and paralyzed the metropolitan area.
