Man blew himself up at Antioch high school, police say

Antioch police officers and bomb squad experts surrounded the area around Live Oak High School on Monday morning where a man in his 50s was found dead. 

A preliminary investigation revealed that the man died as a result of injuries that were "self-inflicted and possibly the result of some improvised incendiary device," said Antioch police Officer Darryl Saffold, a department spokesman. "Whether it was intentional or accidental, we don't know."

The man has not been identified. Police said he did not appear to have any connection to the high school. His body was found at 7:32 a.m. Police said they found wires near the man's body. 

"There are no other known injuries at this time, and we are certainly grateful for that," said Officer Saffold.
 

Aerial photographs showed several police cars and officers standing in the street in the 1700 block of F Street, which is also near a middle school. 

The Walnut Creek bomb squad and the ATF were also on scene as wires were sticking out of the man's body, or seen near his body. Department of Homeland security officials, BART police and K-9 units from the Coast Guard were also there. 

The man's body had suffered trauma, officials said, but there was no evidence of gun casings. 

As a result, classes were canceled at the high school. 

Police asked all residents in the area of F Street between 11th Street and 17th Street to go inside and lock all windows and doors unless they received further official instructions that all is clear. By 3:15 p.m., that all clear was given for the area near F Street by the Contra Costa Sheriff's Office Community Warning System.

No more details were immediately given.
