The Pennsylvania State Police is warning registered sex offenders about a telephone scam that targets them for fraud.
State police said Monday there's been an increase in efforts to defraud them though calls falsely claiming to be from law enforcement.
The agency says callers tell offenders they aren't complying with registration requirements, and sometimes that they have a warrant for the target's arrest.
Callers offer to resolve the problem if the offender sends money.
Police say if someone is not in compliance, the only way to resolve it is for the offender to appear at a registration site or make personal contact with law enforcement.
Police say anyone who's received those calls should give the state police Megan's Law Section the phone number and other information about the caller.
