An Excelsior Middle School was injured (accidental) on a school bus today, at approximately 1:08 PM,  in front of Discovery Bay Elementary School. 

 The incident required emergency services to be called, according to a recorded message sent to parents from Principal Storey, a procedure which  delayed the release of some students.

The Sheriff’s office was called and “it was determined that the 13-year old, female student had brought a knife to school and somehow stabbed herslf,” said Sheriff’s spokesman Jimmy Lee.

The girl received some stitches for the injury. No other students were injured in this incident.

Both the BUSD district and Contra Costa Sheriff are investigating the matter.  Witnesses stated the girl had brought the knife to school for fear of being “jumped.” 

Further details will be reported here when and if they become available.
