The Hershey Fire Department is issuing a warning for Derry Township residents. They said someone is impersonating their firefighters to get into homes.
The department said the impersonators recently showed up at a home claiming they were there to do an inspection and smoke alarm check.
The fire department said while they occasionally do inspections, it's usually not random and is initiated by the homeowner and they will arrive in a marked fire department vehicle.
They also said they never solicit donations over the phone.
Fire officials said if you're suspicious of anyone trying to enter your home, call Derry Township police.
