A former Antioch police officer, Morteza Amiri, was found guilty of civil rights deprivation and record falsification from a 2019 incident where he assaulted a bicyclist and deployed his K-9.

A federal jury convicted a former Antioch Police Department officer on Friday who used his K-9 excessively to bite suspects and “kept a running a bite count that he celebrated with other officers,” prosecutors said.

A former Antioch police officer who federal prosecutors said plotted to hurt and intimidate residents was cleared Friday of three out of five charges he faced in Oakland federal court, his defense attorney said.
