Three men are facing drug trafficking charges following a police investigation that began when one of them allegedly threatened a convenience store clerk.

The Chatham-Kent Police Service said shortly before 7:30 p.m. on Monday, a man entered the Daisy Mart variety store on Grand Avenue East in Chatham and asked to use the phone. When the employee declined due to store policy, the man allegedly said he had a gun and he was going to hurt someone.

Before the man left the store, the clerk saw what appeared to be a handgun and called police.

Following an investigation, officers identified a suspect who was then located at a residence a short distance away and arrested. Two other men were also arrested and officers seized a large quantity of narcotics, along with a replica firearm.

The three men, aged 23, 31, and 40, have all been charged with two counts of possession of a schedule one substance for the purpose of trafficking. The 31-year-old is also charged with possession of a firearm contrary to a prohibition order and uttering threats.

The accused were all held in police custody pending a bail hearing.
