BERKELEY -- A construction crew member working on a new track at Martin Luther King Jr. Middle School was run over by a truck and killed Tuesday, a school district spokesman said.

The worker, who has not been identified, was hit about 12:30 p.m. in what Berkeley Unified School District spokesman Mark Coplan described as a tragic accident. Representatives from Division of Occupational Safety and Health (Cal-OSHA) were headed to the school to investigate the death, Coplan said.

No students were at the North Berkeley school at the time; school starts on Wednesday.
