SAN DIEGO -- One of a four people thrown out of San Diego eatery and pepper-sprayed opened fire on security guards, wounding both of them and the restaurant manager.

The shooting at Dave & Buster's at 2931 Camino Del Rio North occurred Sunday at about 12:40 a.m ., San Diego police Sgt. Rich Nemetz said.

It was unclear what led to the ruckus, but Nemetz said security guards threw out three men and a woman, and fight broke out in which the security guards sprayed the four with the irritant.

The four split into two groups, getting into a green BMW and a black Honda Civic, he said. As the cars pulled out, the driver of the BMW opened fire.

Nemetz said all three victims should recover from their wounds.
