Police used “flash bang” stun grenades to disorient and distract him, Davis said. An FBI hostage rescue team eventually pulled him out of the boat.
Col. Alben said state police flew a helicopter over the area, and infrared images showed that someone was in the boat. He said the capture plan was immediately set in motion.
“We have a suspect in custody,” he said. “We’re exhausted but we have a victory here tonight.”
President Obama, speaking to the nation from the White House, praised police for capturing the suspect, and said the investigation now turns toward determining if any others were involved and what motivated the marathon bombings.
Officials lifted an emergency lockdown of metropolitan Boston at 6 p.m. Friday, 18 hours after it was imposed to protect the public safety. Thousands of residents had been told to stay in their homes and lock their doors.
The announcement allowed businesses to reopen and subways, taxis, commuter trains and buses to roll. They had been closed down throughout the day, turning Boston into a ghost city on a day when streets are normally choked with traffic and sidewalks with shoppers.
Col. Alben told a news conference shortly before the suspect’s capture that a door-to-door search for him in a 20-block neighborhood of Watertown on the western edge of Boston had been fruitless. He later said the capture site was just outside the perimeter of that area.
The manhunt included an army of federal, state and local police officers, assisted by the tactical presence of SWAT teams, K-9 dogs, armored vehicles and helicopters.
Tamerian Tsarnaev, the older brother, died of multiple gunshot and shrapnel wounds in the Thursday night shootout. His brother eluded capture by fleeing the gunfight in a car, running over his brother’s limp body on the ground in the process. Police said he later abandoned the car and fled on foot.
