Seattle SuperSonics legend Shawn Kemp has been charged with first-degree assault from an alleged drive-by shooting in March.

Kemp allegedly shot a gun in a Tacoma mall parking lot after a confrontation between occupants of two cars. No one was injured.

He was released from a Washington jail the next day.

Kemp says he had property stolen from his car and was acting in self-defense, a source close to the former NBA star said. Kemp tracked his missing iPhone to the Tacoma Mall, and when he approached a vehicle, a suspect shot at him, and he fired back in self-defense, he says.

Kemp will plead not guilty, his lawyer, Scott Boatman, told ESPN.

Kemp, 53, spent eight seasons in Seattle, a franchise that moved to Oklahoma and became the Oklahoma City Thunder.
