Dr. Matthew Bonanno, the Long Island plastic surgeon accused of having a cache of weapons, appeared in Tuckahoe Village Court today.

He is due back in village court Monday, unless a Westchester grand jury indicts him before then. The grand jury is to hear the case this week.

DETAILS:More on what happened in court

Bonanno, 47, was arrested last week after someone reported to police that they overheard him in a Tuckahoe bar threatening to kill his estranged wife and family.

He was arraigned last Tuesday in village court on nine counts of second-degree criminal possession of a weapon and 32 counts of third-degree criminal possession of a weapon, all felonies. He is being held in the Westchester County jail without bail.

Tuckahoe police found Bonanno on Aug. 12 at Growler's Beer Bistro on Main Street where he surrendered without incident, District Attorney Anthony Scarpino said.

Police found an arsenal of weapons, ammunition and defensive gear in Bonanno's car and at two known addresses, as well as a loaded semiautomatic handgun in his friend's car, law enforcement officials said.

ARREST: Plastic surgeon's lawyer calls Tuckahoe weapons cache case 'completely out of proportion'

Officers found the following in his BMW SUV parked in his estranged wife's driveway:

five fully loaded assault rifles with high-capacity magazines

three handguns

29 high-capacity loaded magazines

over 1,600 rounds of ammunition

a stun gun

heavy ballistic body armor and a ballistic helmet

handcuffs

full head-cover face masks

multiple military-style knives

four brass knuckles

pepper spray

scopes, binoculars and other paraphernalia

Police said they found three more unlicensed handguns in his Mount Pleasant home, as well as assault rifles, a shotgun, handguns, high-capacity magazines, body armor, hundreds of rounds of ammunition, smoke grenades and other weapons in his Great Neck home.

Paul Gentile, Bonanno's lawyer, described the weapons and tactical gear as part of a firearms collection that Bonanno used at firing ranges and in wooded areas.

“It’s public record that individuals who do collect in firearms and are aficionados of firearms do collect sizable numbers,” Gentile said. “It’s routine in that community.”

Police said there was an order of protection against Bonanno that had expired, but that there was no history of violence between Bonanno and his wife.

“Dr. Bonanno is a well-known, respected plastic surgeon who has been doing terrific work for people for many, many years,” Gentile said, adding Bonanno has no prior criminal record.
