Police vehicles with lights flashing converged on an area near a skate park around 6:30 p.m. after a suspicious male was reportedly spotted in the vicinity.
There was traffic on Twitter about an armed man wearing camouflage clothing wandering about.
Cochrane Mayor Ivan Brooker posted a tweet warning residents to stay in their homes until "RCMP find the armed man in Mitford park area.”
A short time later Brooker tweeted that a suspect had been arrested without incident after Mounties surrounded a home, and that residents could "sleep at ease."
But there was no confirmation from police Sunday night whether the suspect had been armed or whether charges were pending
