Diamond Bar

Latest complete week March 8–March 14

  • Crime reports provided by the L.A. County Sheriff lag behind events, in some cases for a few weeks. Sheriff's officials have said clerical staff shortages delay the processing of addresses needed to map crimes. Because of the delay, The Times’ Crime L.A. database does not provide short-term analysis or alerts about recent rises in crimes for areas patrolled by the sheriff.
  • Below is a list of crimes reported for Diamond Bar in the latest seven days. Keep in mind that the number of crimes reported for this time period may increase over the coming weeks as the Sheriff provides additional data.

600 block of North Diamond Bar Boulevard Aggravated assault March 9, 9 p.m.
