A fifth suspect charged in the fatal beating of a teen in Queens bragged about the attack in anti-gay Facebook postings, law enforcement sources said.

Calvin Pietri, 17, of Woodhaven, was arrested Tuesday night and charged with manslaughter in the weekend beatdown of Anthony Collao, 18.

Police first busted him for a hate crime, but prosecutors later said the bias enhancement was still under review. Pietri was ordered held in lieu of $50,000 bail after his arraignment Wednesday night.

The victim was chased from a birthday party in Woodhaven early Saturday. Police said the teen was stomped and beaten with a pipe. Collao, who hoped to one day work in the family ice cream business, died at Jamaica Hospital on Monday.
