CENTREVILLE (AP) – The mayor of the southwestern Illinois city of Centreville says the assistant police chief is on administrative leave with pay because he is under federal investigation.

Assistant Police Chief Corey Allen told the Belleville News-Democrat (http://bit.ly/U33WdI ) that he hasn't been arrested. He declined any other comment.

Centreville Mayor Marius Jackson released a statement Friday saying Allen had been put on administrative leave "to ensure a thorough and complete investigation ... without the perception of influence."
