The other suspect, his elder brother Tamerlan, died after getting critically injured in an encounter with the police on Thursday night.
A crowd of some 40 people were seen waving American flags and chanting USA! USA! USA! at Watertown Square after the state nabbed its enemy. They exchanged salutes with drivers who blew their horns while riding past and sang "God Bless America".
Celebrations were seen throughout the city after the police found Tsarnaev stained by his own blood and lying in a boat underneath a tarp. An unidentified State Trooper told journalists that the man was finally found and he was in custody, triggering an applause from among the commoners.
The officials were happy that the two-day drama ended without any bloodshed. Three people were killed and several were injured in the Boston bombings near the finish line of the historic marathon while one police officer was shot dead at the Massachusetts Institute of Technology campus on Thursday night. The two suspects, following the death of the police officer, carjacked an SUV and were chased by the police ill they reached Watertown.
State official tells Boston Globe that bombing suspect was 'alive, conscious, captured'.
