Windsor police say three people have been charged and suspected fentanyl has been taken off the streets.
Members of the Drugs and Guns (DIGS) Unit began an investigation last month into potential drug trafficking.
Officers from the Emergency Services Unit executed a raid late Thursday night at a house on Longfellow Avenue near Beals Street West. The three men inside the house were arrested.
A search of the house uncovered 123.2 grams of fentanyl, plus eight cellphones, drug packaging materials, and a digital scale.
The men, aged 38, 31, and 27, are each charged with possession of fentanyl with intent to sell.
The 31-year-old was also charged with three counts of failure to comply with a release order.
The charges have not been proven in court.
