The Cattaraugus County Sheriff’s Office has issued a warning to residents regarding a recent telephone scam.

According to police, a person claiming to be a representative of National Grid has made calls promising to give discounts on bills, but requests personal information such as Social Security numbers or account information. The reported calls appear to come from 808 and 718 area codes.

Police urge residents not to give out any personal information or return any calls to these numbers. If such a call is received, call your local police agency.
