OAKLAND — Two men were wounded in a West Oakland shooting Wednesday night, authorities said.

A woman who was with them was not injured.

Both men, one 40 and the other 49, were in stable condition at a hospital.

The shooting, which prompted the activation of a gunshot detection alert system, happened about  11:10 p.m. Wednesday in the 1100 block of 32nd Street, a mostly residential area.

According to initial police reports, the two men and the 34-year-old woman, who all know each other, were standing outside when at least one person and possibly more began shooting at them.  Police were trying to confirm if the shots were fired from a passing vehicle or if the shooter or shooters were on the street.

The men shot were taken from the scene by ambulance to a hospital. It was not immediately known if they lived in the area.

Police said dozens of shell casings were recovered at the scene.

A motive for the shooting is under investigation.  No arrests have been made and no suspect information has been released.
