Police are warning people about a new scam threatening immigrants in U.S.

Police are warning people about a new scam threatening immigrants or people from Mexico with graphic videos.

A Pasco, Washington man received a gruesome video of three men getting stabbed to death on WhatsApp then threats saying that if he didn't send money it would be him in the next video. The man contacted Pasco police, and now they're warning others that this could be more widespread.

“If it doesn't look right, if it doesn't smell right, don't do it,” said Sgt. Scott Warren with Pasco police.

Police don't know where the horrific video . . .
