Sheriff's deputies in Volusia County said three 18-year-olds, Nicholas Kaye, Austin Cowling and Steve Tilbury, beat up their friend, held a gun on him, and stole his iPhone.
Deputies said the three suspects wanted the victim to steal alcohol and he refused, so the beating ensued.
The victim, also 18, told investigators that the suspects showed up at his Deltona home just before 11 p.m. and drove him to a store, demanding he steal first a bottle of liquor, then beer.
The teen was punched and kicked because he did not want to carry out the theft, investigators said.
The suspects were booked into the Volusia County Jail on several charges.
