A carjacking at a gas station led police on a pursuit through Fairmount Park late Wednesday night.

Philadelphia Police Chief Inspector Scott Small told CBS News Philadelphia it all started when a 66-year-old man was pumping gas at a station along the 7200 block of Roosevelt Boulevard when two men approached him.

One of those men pointed a gun at him, went through his pockets, took his keys, and fled in his Nissan Rogue along with another suspect, according to Small.

Small said the victim left his phone in the car and because of that, a family member was able to track the phone. In about 20 minutes, Highway Patrol officers located the vehicle at the intersection of Girard and Belmont Avenue and that is when a pursuit ensued. 

After it went for a few blocks, the suspects then rammed the officer's vehicle at the intersection of Montgomery Drive and Belmont Avenue. The pursuit then continued a few more blocks before the suspects bailed out of the vehicle. That's when police say one of the suspects fired a shot at police at Montgomery Drive and Martin Luther King Jr. Drive.

Highway Patrol officers, along with Philadelphia Police, then pursued the three suspects on foot. The suspect who fired a gun, later identified as a 16-year-old, was apprehended on the train tracks and his firearm was recovered. The other two suspects, both 17 years old, were caught a short time later, Small said. 

All three suspects were identified by the 66-year-old man who was carjacked at the gas station. Small said he was not injured but shaken up by the incident. The two Highway Patrol officers who were rammed by the suspects were also not injured.
