Wellington County OPP say they’re investigating a home invasion in the Town of Erin.

Around 8:45 p.m. Thursday, OPP say, multiple people entered a home on County Road 125, northeast of Rockwood and northwest of Acton.

The group left just before police arrived, but it’s believed at least one intruder was armed with a gun.

Once inside, police allegedly discovered an active marijuana grow-op in the residence.

Police continue to investigate, and want to hear from anyone who may have information regarding the home invasion or other suspicious activity in the area.
