(REUTERS) -- Several media sources are reporting that a house in Watertown has been surrounded, and that explosions were heard inside the home. This, as a massive manhunt continues for the one surviving Boston Marathon bombing suspect.
About five hours after the FBI released the pictures of the bombing suspects, a police officer was shot and killed on the campus of Massachusetts Institute of Technology, the Middlesex County District Attorney said in a statement.
A short time later, police received reports of a carjacking by two men who kept their victim inside the car for about half an hour, the statement said.Police pursued that car to Watertown, where explosives were thrown from the car at police and gunfire was exchanged, the statement said."During the exchange of the gunfire, we believe that one of the suspects was struck and ultimately taken into custody. A second suspect was able to flee from that car and there is an active search going on at this point in time," Colonel Timothy Alben, superintendent of the Massachusetts State Police, told a news conference.Police killed one suspect in the Boston Marathon bombing during a shootout and were engaged in a house-to-house search for the other on Friday in the Boston suburb of Watertown."What we are looking for right now is a suspect consistent with suspect No. 2, the white-capped individual who was involved in Monday's bombing of the Boston Marathon," Alben said.(By Scott Malone; Additional reporting by Alex Dobuzinskis in Los Angeles and David Bailey in Minnesota; Writing by Daniel Trotta; Editing by Mary Milliken and Lisa Shumaker)
