SAN LEANDRO -- A San Leandro police officer is being lauded by the department for possibly saving a suicidal man's life Tuesday night.

At 6:15 p.m. Tuesday, an officer on patrol spotted a 30-year-old San Leandro man sitting on the railing of a bridge that crosses the San Leandro Creek watershed in the 1100 block of Bancroft Avenue.

The officer, who has had previous contacts with the man, suspected the man might be attempting to kill himself by jumping off the bridge to the ground 30 feet below, police Lt. Mike Sobek said.

As the officer approached, the suicidal man fell backward toward the officer, who called for assistance from other officers. The officers controlled the man and no one was injured, Sobek said. Sobek said the officer asked that his name not be released.

"Our officer's keen observation skills, beat knowledge and quick action prevented this man from taking his own life," Sobek said. "His actions epitomize one of a police officer's core responsibilities, and that is to save lives."

Police spoke to the man, who confirmed to officers that he intended to take his own life. The man was placed on a psychiatric hold and transported to a hospital, police said. The man's name was not released.
