Three men were arrested at an off-campus student housing complex near the University at Buffalo’s North Campus following a dispute involving narcotics, Amherst police said Tuesday.

Authorities received a call at about 10:30 p.m. Monday about a man, identified as Jacob Schiller of Amherst. Police said they were told he was upset and may “take matters into his own hands.”

When they arrived at the housing unit at the Villas at Chestnut Ridge on Nickel Way, officers found Michael Sussman of Tonawanda lying on the floor with his hands bound behind him with flex cuffs, police said.

Investigators believe Schiller was upset with Sussman for allegedly providing narcotics to an acquaintance.

Police then found an “associate” of Sussman’s, Jeffrey Barber of Kenmore, in the parking lot and took him into custody.

During the investigation, police also found an inoperable handgun in the kitchen trash.

Sussman and Barber were charged with conspiring to commit a narcotics felony. Schiller was charged with felony assault, menacing and criminal possession of a weapon.

All three were arraigned in Amherst Town Court. It was not clear whether any of them were students.
