A cyclist was left clinging to the roof of the car that hit him early this morning, shortly before the speeding driver flung him off and fled the scene.

The unidentified 18-year-old bicyclist was riding on Northern Boulevard around 1:50 a.m. this morning when a driver ran a red light and smashed into the bicyclist, who clung to the roof of the dark-colored car. The cyclist held on to the roof from where he was hit, on 54th street, until he was flung from the car when it turned on to 53rd Place. All the while on the roof, the bicyclist was trying to get the driver to stop their car.

"The guy was laid out on the roof, banging with his hand and yelling, 'Stop! Stop! Stop!' like panicking," a witness told the Daily News. "The guy went flying off the front of the car. He went rolling on the street."

The cyclist was taken to Elmhurst Hospital in serious, but stable condition. The motorist sped off after throwing the bicyclist to the ground. Police are still searching for the driver of the car, which might have been a livery cab.
