Northern California man dies after police stun gun clash

REDWOOD CITY, Calif. (AP) - Authorities are investigating the death of a Northern California man who was suspected of attacking his 83-year-old mother and died after police shocked him with a stun gun.

Fifty-five-year-old Ramzi Saad of Redwood City was pronounced dead at a hospital after the Monday evening confrontation.

Police say they were called to a home by a neighbor who said Saad had assaulted and threatened to kill his mother and neighbors weren't able to restrain him.

Police say Saad attacked an arriving officer. The struggle eventually involved four officers.

San Mateo County District Attorney Steve Wagstaffe says Saad was shot two or three times with a stun gun. He collapsed, stopped breathing, and died at a hospital.

His mother wasn't seriously hurt.

Wagstaffe says Saad had a history of mental health problems.
