SCHAUMBURG, Ill. (CBS) -- Three Schaumburg police officers have been arrested, following a federal drug investigation.
The officers were placed on administrative leave, pending the results of the criminal investigation. They've been accused of stealing money and drugs from narcotics dealers, and then selling the drugs themselves.
The officers have not been identified, but sources told CBS 2's Pamela Jones they are tactical officers, who are members of a special investigation unit. They were being held at the DuPage County Courthouse in Wheaton.
The DuPage County State's Attorney's office said the three officers were scheduled to appear for a bond hearing Thursday morning at 8 a.m.
Sources said federal investigators have been searching lockers and an inventory room at the Schaumburg police station.
Wednesday night, armed officers descended on the Algonquin home of one of three Schaumburg police officers who was arrested. Police taped off the property and searched for evidence, then later allowed a woman and two children to enter the home.
It was all quiet at the Streamwood home of another of the accused officers Wednesday night, but neighbors said hours earlier the street was lined with unmarked police cars.
In a statement, Schaumburg Police Chief Brian Howerton said, "The Village and the Schaumburg Police Department have been in contact with the DuPage County State's Attorney's Office and it has pledged its ongoing assistance to investigators going forward."
The village also launched an internal investigation of the officers' actions.
