Police in Dobbs Ferry said a Mercy College student was arrested during Ferry Festa last weekend at about 2:10 p.m. after officers observed him remove an item from his backpack and hide it in the front of his pants.
Police said the 19-year-old from Yorktown Heights initially refused to turn over the item, but eventually gave police a clear plastic bag with seven more clear plastic bags containing "a white rocky substance" believed to be MDMA drug known as "Molly."
Nicholas J. Caruso also had a box of Bud Light beers in his backpack and a small bottle of Ciroc vodka, police said.
He was arrested at the scene, charged with D Felony Criminal Possession of a Controlled Substance in the Fourth Degree and a violation for possessing alcohol under the age of 21.
He was arraigned and later released on $7,500 bail with a returnable court date.
Also on October 5, police issued three tickets on Main Street to under 21-year-olds who had allegedly had open alcoholic containers, the department said.
An 18-year-old Farmingdale man, a 19-year-old East Meadow man and a 19-year-old Syracuse man all had cups with beer on the street, police said.
