A Harvey teen was ordered held in lieu of $100,000 bail Sunday after he allegedly brought a loaded handgun and several bags of marijuana to school on Friday.

Marquise D. Roy-Lewis, 16, of the 14800 block of Cooper Avenue in the south suburb, is being charged as an adult in the case, according to Assistant State's Attorney Joel Bruckman.

Roy-Lewis faces a felony unlawful use of a weapon charge for allegedly bringing a .22 caliber gun to Harvey's Thornton Township High School, according to court records. It was not clear Sunday if the teen was a student at the school.

He also faces possession of cannabis charges in connection to Friday's incident, according to court records.

Before setting his bail Sunday in Cook County Bond Court, Judge Adam D. Bourgeois Jr. told Roy-Lewis that there was nothing he could do for him.

"We've got too many people in this country who think they can walk around with weapons," Bourgeois said before setting the teen's bail.
