(Chicago)  A Cook County juvenile court judge ordered the teen charged with mugging Mayor Rahm Emanuel’s son be held in custody given the boy’s frequent contact with law enforcement.

Cook County Judge Lori Wolfson noted that the teen had frequent contact with the court system, the Sun-Times is reporting. He has been arrested 11 times and has had 32 contacts with the Chicago Police Department, authorities said.

The 18-year-old also was found guilty in October of possession of a stolen motor vehicle and was sentenced to one year of probation.

The teen, whose name was not released, was arrested Saturday for the Dec. 19 robbery of Zach Emanuel in the 4200 block of North Hermitage, Chicago Police announced Saturday night.

He “confessed to the crimes he committed” and is charged as a juvenile with robbery and aggravated battery in the public way, according to a police statement. He was 17 at the time the crime is alleged to have been committed.

His trial date for the mugging is March 9.

His parents left juvenile court Monday without comment.
