Police are searching for the driver who hit a man and dragged him nearly two blocks before speeding away.
Philadelphia Police say the unidentified man was struck around 4 a.m. along the 600 block of Ontario Street in the Kensington section of the city.
A witness told officers he found the 45-year-old man sleeping in the middle of the street. The witness said he tried to wake the man, but couldn't.
The witness left to get his phone to call 911, when he saw a car turn around the corner. The man told police he tried to stop the dark blue Chrysler 300 sedan with silver trim, but it just kept going.
The man was run over and dragged about a block and a half from Ontario Street to Crystal Street, according to police. The vehicle then fled the scene.
The victim was taken to Temple University Hospital in North Philadelphia in critical condition.
Philadelphia Fire Department crews were called to the scene to clean up the roadway following the crime.
Police say the vehicle was described as a private limo town car or taxi cab. It had a taxi cage, or partition, between the front and back seats.
Authorities have a partial license plate of "LM." They ask anyone with information call 911.
