KINGSTON, Jamaica (AP) — Western Union has set a money transfer limit of $400 in a northern Jamaican parish that is the hotbed for a multimillion-dollar lottery scam that targets mostly elderly Americans.

Company spokesman Daniel Diaz said Wednesday that Western Union has imposed the tighter controls on outlets in St. James parish, which includes the resort city of Montego Bay.

The money transfer company shut down its locations in the Jamaican parish earlier this month while it conducted a systems review. Diaz says it has restored service to three locations in the parish now that the new transfer limits have been imposed.

Jamaican scam artists often use disposable cellphones to cheat mostly elderly Americans out of their savings by enticing them to transfer money to claim winnings from a phony lottery.
