Authorities in Jamaica have arrested a couple suspected of involvement in a lucrative lottery scam.

Police say the couple is being investigated for identity theft after officers searching their home found lists of names of people living overseas along with several debit cards issued by foreign banks.

Jamaican has been trying to crack down on a local multimillion-dollar lottery scam targeting mostly elderly Americans out of their retirement savings. Jamaica and the U.S. have created a task force to target the schemes, which are estimated to generate at least $300 million a year.

Police said the couple was arrested Friday in the popular northern tourist district of St. James.
