The scammers are back in Chevy Chase, and this time, they're pretending to be your grandchildren.

Approximately five Friendship Heights residents have been contacted on the telephone since mid-October by someone pretending to be a grandchild and asking for money, according to Montgomery County police.

The scammer claims to have been arrested or involved in an accident in Mexico or Canada, asks that money be deposited into a bank account and provides the bank account's number. The scammer also asks that his or her parents are not informed, police reported.

In two of the incidents, victims transferred $2,000 to a scammer, police added.

Police warned residents to be on their guard: "Obtain a telephone number from the caller, and tell the caller that you will return his or her call. Do not provide bank account numbers over the phone, and do not send money to anyone you do not know."

Police asked residents to contact the police if they think they might have been contacted by a scammer.

"Your report to the police is [often] the only way that police know that such incidents are occurring," police added.

Recent alleged scams in the Chevy Chase area include a utilities scam, a mailbox scam and a sports team scam.
