OAKLAND -- Two people escaped with their lives after a man fired shots during an armed robbery at the Martin Luther King Regional Shoreline Park on Sunday night, police said.

The victims were walking in the Damon Marsh area off Oakport Drive, north of 66th Avenue, when the robbery occurred about 9:15 p.m., according to East Bay Regional Parks police Lt. Jon King. They were walking in a park when three men approached, one of them showing a gun.

The trio demanded money, a cellphone and one of the victims' car keys, King said, and at least one of the suspects punched both victims in the face. The victims adhered to the demands, then ran into the park to escape while one of the suspects fired a gun, King said

Nobody was hit by the gunfire, and the victims weren't injured.

All three suspects appear to be between 16 and 20 years old and Hispanic, King said. One of them was wearing a black-hooded sweatshirt and jeans; a second was wearing a black hat, white shirt and jeans and a third was wearing a gray sweater and khaki jeans. They were last seen driving a black Buick with stock rims and tinted windows, King said.

Anyone with information is urged to contact East Bay Regional Parks police at 510-881-1833.
