PORTLAND – The owner of a Windham escort service has been charged with trying to extort money from a longtime client, according to federal court documents.

Nicholas Enfanto of Saugus, Mass., was arrested May 4 and charged with sending threatening interstate text messages to extort money from the client, identified in court documents as “J.D.” from Falmouth.

According to an FBI affidavit filed in federal court in Portland, J.D. had been a client of Enfanto’s Perfect Pleasure Escort Service, based in Windham, for at least eight years. J.D. told officials that he never paid the escorts directly, but mailed payments to Enfanto in Massachusetts.

In February, Enfanto sent J.D. text messages, accusing him of contacting escorts directly without going through Enfanto, the affidavit said. Enfanto claimed that J.D. owed him $100,000 for lost business and allegedly threatened J.D., saying at one point that he would shoot J.D. if he didn’t pay, the court documents said.

J.D. agreed to pay Enfanto $250 a week, but in late April, Enfanto told J.D. he was increasing the amount to $400 a week, according to the FBI . When the intensity of the threats picked up, J.D. went to Falmouth police, who brought in the FBI.

Enfanto sent a series of obscenity-filled texts threatening J.D. in late April and early May, according to the court documents. The FBI determined they had been sent from Massachusetts, leading to the federal charges due to the interstate transmission.

Enfanto made an initial appearance in federal court Friday and was ordered held pending a detention hearing. If convicted, he could face up to 20 years in prison and a fine of up to $250,000.
