SHEFFIELD, Ala. (WHNT) – Sheffield Police officers are responding to calls of a door-to-door solicitor.

Certified Alarm Co. also sent out an alert on their Facebook page. It says a man is going around claiming to be an employee there. They say he’s trying to trick customers into switching alarms.

The post said they man is not affiliated with the company at all. Certified Alarm never solicits in that manner.

They’re asking that you warn your neighbors of the scammer.

If he knocks on your door, you can call Sheffield Police at (256) 383-1771.
