Lathrop Police Services wants you to know that if the person on the phone is offering you something that sounds too good to be true, it probably is. For the last month, the San Joaquin County Sheriff’s Department and Lathrop Police Services have been warning local residents about an ongoing phone scam in which callers pose as representatives of a financial institution, offering to cut interest rates on credit cards. By using a fake caller ID tag and using a number that cannot be traced, the callers “fish” for information that can be used against their victims at a later date.
