A Mount Prospect police officer is on administrative leave after he was arrested on domestic violence allegations last month.
Sgt. Anthony Lietzow, 44, of Huntley is charged with domestic battery, aggravated battery to a peace officer and resisting a peace officer after an altercation at his home July 19, according to a police report.
A McHenry County judge required that Lietzow surrender his firearm as a result of the arrest. The department placed Lietzow on administrative leave because he doesn't have a weapon, said Police Chief Tim Janowick.
Janowick said the department is also investigating the arrest.
"We're conducting our internal investigations. When we reach a level where we're able to conduct discipline, we're going to do that," he said. "It's going to take some time."
Lietzow has been a highly decorated member of the Mount Prospect Police Department for more than a decade. He has served as a patrol officer, narcotics officer and a member of the Major Case Assistance Team, and was named the department's officer of the year in 2005, 2007 and 2009.
He also received the Cook County Sheriff's Award of Merit in 2006. He was promoted to sergeant in 2014.
A call to Lietzow's attorney was not returned Wednesday. He is scheduled to appear in court on Sept. 1.
