A BOGUS security company has been offering to fit free house alarms and sometimes claiming to be working for the police.
The cold calling scam has been thwarted by plucky residents who have questioned the so-called offers.
Sussex Police officers do not think any crimes have been committed but are warning people to be on their guard.
Residents in London Road, Newlands Avenue and Glenthorn Road in Bexhill have been targeted.
Bexhill neighbourhood policing team inspector James Scott said: “Our advice is to never let anyone into your home who you do not know or who you have not arranged to come around.
“Don’t feel pressured into letting this sort of person in to your house or carry out work you are not fully happy with.”
Report suspicious activity to the police at any time by emailing email@example.com or calling 101.
