South San Francisco police are warning the public of a scam that involves claiming someone's family member is being held for ransom.
A woman told officers that an unknown caller contacted her around 3:30 p.m. last Tuesday, police said.
The caller told her that he was holding one of her family members for ransom and instructed her to send $5,000 through Western Union to an undisclosed location in Mexico, according to police.
If the woman did not fulfill the task, the caller told her he would harm the family member, police said.
The caller knew the family member by name and the person's relation to the woman, according to police.
The woman did not send the money and contacted police.
Police did not immediately know how the caller knew the woman's personal information.
Anyone with information about the case is asked to call South San Francisco police at (650) 877-8900.
