(CNN) Four Missouri police officers have been indicted by a federal grand jury in connection with the assault of a fellow officer who was working undercover. Officers Dustin Boone, Randy Hays and Christopher Myers with St. Louis Metropolitan Police Department (SLMPD) are accused of beating the undercover officer with a riot baton and tampering with witnesses to cover up the incident, according to the Department of Justice. Officer Bailey Colletta was indicted on a charge of providing false statements to a federal grand jury in connection with the incident. CNN attempted to reach the city of St. Louis, the SLMPD and associations representing the officers, but has not received a response. In September 2017, all four officers were assigned to a Civil Disobedience Team, which conducts crowd control, in anticipation of a protest against the acquittal of Officer Jason Stockley, the US Department of Justice said in a news release.
