(CNN) — The second suspect in the Boston Marathon bombings was taken into custody Friday night, bringing to an end a massive manhunt in the tense Massachusetts capital worried by warnings the man was possibly armed with explosives.
After announcing the arrest on Twitter, Boston police tweeted: “CAPTURED!!! The hunt is over. The search is done. The terror is over. And justice has won. Suspect in custody.”
Authorities confirmed the man in custody is 19-year-old Dzhokar Tsarnaev, who escaped an overnight shootout with police that left his older brother Tamerlan Tsarnaev — the other man wanted in the bombings — dead.
The younger Tsarnaev was in serious condition at an area hospital, Boston Police Commissioner Ed Davis said at a news conference.
Tsarnaev was cornered late Friday as he was hiding on a boat in a backyard of Watertown, a suburb of Boston.
Police were alerted to his whereabouts by a man who went outside after authorities lifted an order for residents to stay inside during the manhunt. The man saw blood on a boat in the backyard, Davis said. He then lifted up the tarp covering the boat and “saw a man covered with blood,” he said.
It was that call that resulted in an arrest less than a week after two bombs exploded near the finish line of the Boston Marathon, shocking the nation and leaving a city on edge.
“There was an exchange of gunfire, and I don’t know if he was struck,” Davis said of the suspect.
Authorities, using a bullhorn, had called on the suspect to surrender: “Come out with your hands up.
Tsarnaev, according to authorities, refused to surrender.
“We used a robot to pull the tarp off the boat,” David Procopio of the Massachusetts State Police said. “We were also watching him with a thermal imaging camera in our helicopter. He was weakened by blood loss — injured last night most likely,”
Tsarnaev was taken into custody after authorities rushed the boat, Davis said.
The standoff and subsequent arrest came just minutes after authorities indicated during a news conference that a manhunt for the suspect appeared to come up empty.
Authorities had cast a wide net for the suspect, virtually shutting down Boston and its surroundings after a violent night in which authorities say the brothers allegedly hurled explosives at pursuers, after killing Massachusetts Institute of Technology police Officer Sean Collier and hijacking a car.
“We’ve closed an important chapter in this tragedy,” President Barack Obama said in a televised address. Even so, he vowed to seek answers to the motive in the attack and find out whether the suspects received any help to carry out their plot.
