A case of supernatural blackmail has become a Detroit police matter.

Police in Hoboken, N.J. say a woman reported being cursed by three friends after she informed on someone regarding a police incident more than three years ago.

The victim was told, although it unclear by whom, that she would have to visit a palm reader on Arlington in Detroit to have the curse removed.

Hoboken Police Sgt. Sam Williams confirmed, based on the woman's statement, that she visited the palm reader as requested and paid $2,000 for the lifting of the curse.

It didn't work.

Two weeks later, the victim felt the curse still loomed and called the Detroit mystic again for help.

Williams said the palm reader told the New Jersey woman that the curse had been reinstated; to lift it would require a bit more money.

The victim obliged - for at least a while - paying over $2,000 throughout the next two years.

The victim stopped paying the clairvoyant's mystical ransom about four months ago, prompting the psychic to take action.

Police say the palm reader began making threatening calls every several months, requesting money, or else a curse would be cast.

It is unclear if the Detroit palm reader followed through with the threat, but the actions did result in the woman contacting police.

Williams said he could not reveal the identities of the victim or palm reader because the investigation remains open.

It has been forwarded to the Detroit Police Department for investigation. The Detroit Police Department Public Information Office could not be immediately reached for comment as of about 10:50 a.m. Tuesday.

Williams said the actions of the palm reader are potentially illegal and could be considered "theft by deception."

"It's not the first time" something like this has happened, Williams said. "I'm sure it won't be the last."
