Three juveniles were arrested Tuesday in connection to at least “16 potential carjackings” on Chicago’s south and west sides, police said.

Chicago Police Department spokesman Anthony Guglielmi said he couldn’t release many specifics because there are “two additional offenders that we are seeking to apprehend.”

In a tweet, Guglielmi said the teens were involved in a “carjacking pattern” that occurred from Halloween to Nov. 19.

He said the juveniles will face vehicle and identity theft charges in the juvenile court system.

It was not immediately clear if the charges had been approved yet.

There have been about 700 carjackings reported this year.
