ST. LOUIS • A teenage girl claims in a lawsuit filed Thursday that she was falsely arrested by a city police lieutenant who did not approve of her seeing the officer's son.

The suit in St. Louis Circuit Court names the Board of Police Commissioners and some officials who it alleges tried to cover up the actions of Lt. Henrietta Arnold.

The plaintiff, identified in documents only by the initials S.L., claims that Arnold and Officer Susie Lorthridge were on duty when they arrested her July 3 at Arnold's home in north St. Louis County, while she was visiting at the invitation of the lieutenant's son.

The suit claims the girl was returned to the city to be processed at the North Patrol Division and detained in the city jail for about four hours. It claims that Arnold and Lorthridge falsely reported that the incident occurred at a business with a city address.

The filing also alleges that after attempts to have the incident report approved in the district where the arrest allegedly happened, it was later approved in another district by Sgt. Lathan Isshawn-O'Quinn, who serves under Arnold's command.

In addition, the suit faults Chief Daniel Isom, and Cols. Antoinette Filla and Reggie Harris, who it claims failed to discipline the officers in a timely manner.
