RESIDENTS are being warned to be on their guard against bogus callers.

The warning comes after reports of callers in the Liden and Park South areas of Swindon pretending to be working for a gas company.

A spokesperson for Swindon Police said: "Residents are reminded of the need to check the identity of any callers at their homes before allowing them access.

"If you are unsure of any callers contact the police."
