A man is in jail accused of firing at an off duty-cop and leading police on a chase.

San Diego Police say the man was speeding in National City and almost side swiped the car of an off-duty officer just before 8pm Monday.

The cop then followed the driver to get a license plate number.

He says the driver shot at his car three times, so he radioed for help... He wasn't hit by any gunfire.

Officers arrested the driver in chollas view and they did find a weapon.
