Four people face charges after an investigation in Hensall Friday.
The investigation began after an assault on Monday that left one man with non-life threatening injuries.
Multiple OPP units, including the Emergency Response Team and Canine Unit, were at a Richmond St. S address where officers found a quantity of cannabis marijuana as well as a stolen firearm.
Four people inside the home at the time the warrant was executed and all four were charged with multiple drug and weapons offences.
A 36-year-old man, 36-year-old woman, 29-year-old woman and 23-year-old man, all from Bluewater, face charges.
All four were at a bail hearing Friday in Goderich and have been remanded into custody for another bail hearing on Tuesday.
