WILMETTE, Ill. (CBS) — A 17-year-old Chicago boy has been charged in an attempted carjacking this week in north suburban Wilmette, while another suspect has also been arrested and a third remained at large late Wednesday.

At 7:49 p.m. Tuesday, a victim told police he was loading items into his vehicle in the alley behind the 1000 block of Linden Avenue when three male suspects came up and demanded the keys to the car. The suspects implied they had a weapon, but did not display one, police said.

The victim ran away and called 911 at a neighbor’s home, and the suspects ran off, police said.

Wilmette police officers began searching for the suspects and put up a social media post, which led to many calls from neighbors who said the suspects had been spotted, police said.
