Police are searching for two suspects who they say shot a man after contacting him about a dirt bike for sale through the online classifieds site Craigslist.
Detectives said the suspects and the dirt bike owner got into an argument when the two men tried to start the bike and take off without paying.
One of the men pulled out a handgun and pointed it at the victim's chest, firing after his accomplice yelled, "Shoot him," according to police. The pair then stole the bike and fled south on North 5th Street and then west on Erie Street, according to officials.
Witnesses rushed the the victim in their car to Temple University Hospital, where he underwent emergency surgery.
Police are asking for the public's help identifying the suspects, who can be seen riding the Yamaha on the sidewalk in surveillance video.
Authorities describe the shooter as a 20-year-old male, who is 5-feet and 4-inches tall and weighs approximately 150 pounds. He can be seen wearing dark-colored clothing in the surveillance footage.
The second suspect is described as a 20-year-old male, who is 6-feet tall and weighs about 250 pounds. He was wearing a gray sweat suit and a white t-shirt during the incident.
Officials say the dirt bike is an older model white Yamaha 125 with decals posted all over the frame.
Investigators say anyone who sees the suspects should not approach them and call 911. Anyone with information on the suspects or the incident is asked to contact the police tip line at 215-686-TIPS.
