Wagstaffe said the case was submitted to his office on Wednesday and the case was under review.

“I am not going into any detail about the facts of the case since we are reviewing the police reports and have not decided whether charges will be filed,” said Wagstaffe. “If we determine to file charges, I will go into the facts in more detail at that time.  Since arraignment is not until July, my prosecutor will take his time and carefully review the reports and if needed, ask for additional investigation.  So I do not think this decision will be completed in the coming days.”

Chan has been an officer with the San Francisco Police Department since July of 1997, according to Rueca.
