A Vicksburg man was held without bail Saturday on weapons charges.

William Callahan, 30, who lives on Halls Ferry Road, was arrested following a traffic stop at about 12:30 p.m. Saturday by Vicksburg police Investigator Bobby Jones and charged with possession of a stolen firearm, Vicksburg police Lt. Sandra Williams said.

Callahan was convicted of sale of cocaine in August 2007.

The gun was found in Callahan’s vehicle when Jones stopped him for not wearing a seat belt, Williams said.

Callahan was held Saturday in the Issaquena County Correctional Facility awaiting his initial appearance Monday in Vicksburg Municipal Court.
