PORTLAND — A federal grand jury today indicted a New York man on a charge of possession with the intent to distribute 100 or more grams of heroin.

Raydani Genao, 26, was arrested last week after a Maine State Police trooper pulled over a northbound vehicle north of the York toll plaza on the Maine Turnpike.

Genao, another passenger and the driver gave conflicting accounts about where they were going and what they were doing in Maine, according to an affidavit filed by U.S. Drug Enforcement Administration agent Paul Wolf.

After a police dog indicated the presence of narcotics in the vehicle, the trooper found a package containing about 150 grams of heroin, according to the affidavit.

Genao said he had obtained it for $51 per gram in New York and was planning to sell it to a customer in Maine for $60 per gram, according to the document.

The charge carries a penalty of five to 40 years in prison.
