After a bombing injured 29 people in a New York City neighborhood on Saturday, surveillance videos show the same man near the site of the explosion and another location where a pressure-cooker device was found four blocks away, multiple local and federal law enforcement sources told CNN.
Saturday’s explosion shook New York City’s Chelsea neighborhood, packed with restaurants, subway stations, shops, businesses and art galleries, and sent panicked people scrambling for cover. By Sunday, 26 of the injured who had been admitted to hospitals had been released.

Police scoured the area for clues about who was responsible for the explosion and a motive.

A few blocks away from the blast site and shortly after the explosion occurred, investigators found one possible lead: a pressure cooker, with dark-colored wiring sticking out, connected by silver duct tape to what appears to be a cellphone, officials said.

Surveillance videos from Saturday shows the same man near both sites, multiple sources told CNN.
