A woman attacked a limousine driver at knifepoint and stole his vehicle Tuesday night in the city's Crescentville section, but was later tracked down by police using a GPS system located in the car.

Around 7 p.m., the 2010 Chrysler 300 with limousine tags had arrived to pick up a taxi fare in the 700 block of Adams Avenue when a 30-year-old woman jumped into the backseat, Chief Inspector Scott Small said.

The woman put a knife to the 40-year-old driver's throat and ordered him to get out of the car, Small said.

Instead, the man tried to grab the knife and suffered cuts to his hands, Small said. The woman dropped the knife, but then allegedly pulled a gun, and that's when he got out.

"We're not sure if it's the woman who called or not," Small said.

The man called police and told them the Chrysler was equipped with a GPS system, which the police began tracking on the ground and from the department's helicopter, Small said.

The car was located in Abington pulling into a parking lot in the 800 block of Huntingdon Pike, Small said. The woman fled the vehicle and was apprehended nearby.

The car was being held as a crime scene, but the bloody steak knife could be seen inside, Small said.

The man was taken to Aria Health-Frankford Campus, where he was reported in stable condition.
