Four people have been arrested in a drug trafficking investigation in Windsor. An investigation was launched earlier in this month after police said a suspect was believed to be distributing illicit substances at Bruce Park on Church Street. Just before 8 p.m. on Thursday, police executed a search warrant at a home in the 600 block of Bruce Avenue. It interrupted suspected drug activity at Bruce Park and the Windsor Police Service said several ran from the area. Four suspects were arrested after a short chase. Items seized includes: A 21-year-old, 22-year-old, 24-year-old, and a 30-year-old are all facing drug-related charges.
