Santa Monica Police detectives are conducting an investigation of fraudulent use of a cell phone.

Police say a victim received a text message on a cell phone stating that there was unusual activity on the victim’s debit card account and that the victim should call the number left on the text message for verification.

When the victim returned the call, the automated voice message asked the caller/victim to input the account number and personal identification number for the debit card, according to police.

At a later date, the victim discovered that an unknown person had made an unauthorized withdrawal from the account.

Police are investigating the case.

The Santa Monica Police Department advises anyone receiving this type of text message on a cell phone or in an e-mail not to give confidential banking information, such as a personal identification number, to anyone.

Anyone with information regarding this or other scams, is asked to call the Santa Monica Police Department, (310) 458-8491 or Santa Monica Police detective Maury Sumlin (310) 458-8437.

Callers who wish to provide anonymous information may also call the We-Tip national hotline at 1-800-78-CRIME. Callers with information that leads to an arrest and conviction become eligible for a reward of up to $1,000.
