SAN ANTONIO -

Two men are in custody after leading a National Park Service officer on a chase through the city's southside and trying to hit him with their car.

It happened at about 3 p.m. Saturday on Mission Road near Stinson Field.

A National Park Service officer was attempting to initiate a traffic stop when the two men in the car took off speeding.

Although it's not clear why the National Park Service officer was trying to stop the men in the car, they did drive away, leading the officer on a chase down Harding until they got to the 200 block of Shannon.

That's where sheriff officials said the men charged at the officer with the car, as if they were going to run over him. The officer fired a shot at them and they were quickly apprehended.

Abel Leal, a witness on the scene, said the men were traveling at a high rate of speed.

"It looked like a regular traffic stop," said Leal. "He put his lights on to pull him over and he just floored it. He took off."

Leal said the men almost hit a cyclist during the pursuit.

Bexar County Sheriff officials were called to assist in the chase and they have now taken over this investigation.

Philip Dreyer with the Bexar County Sheriff's Office said that the suspects threw something out of the window, but they haven't been able to find anything.

As far as the men in the car, it's not clear what charges they will face at this time.
