Police subdued a man who had allegedly threatened bystanders and officers with a 20-inch machete on Monday afternoon in a Costco parking lot.

The Suffolk County Police Department said officers arrived on the scene shortly after 1 p.m., following numerous witness reports of a naked man waving a machete at people in the lot on Middle Country Road in Lake Grove. The suspect then barricaded himself in the cab of a 2007 Freightliner tractor-trailer, which police said he was operating for a New Jersey-based transport company but was also where he was living.

According to police, the man refused to exit his vehicle when Sgts. Keith Serper and Brian Michels and officers Richard Regula, Christopher Tenbrink, Anthony Sepe and Jean Hutchinson arrived on the scene. But he later attempted to leave the tractor-trailer cab with the machete in his hand, and the officers held the doors shut to contain him. Police said the suspect opened a small window and tried to exit the cab through it, and threatened the officers with the weapon.

Regula, Tenbrink and Serper approached the man closely enough to discharge a Taser. Police then entered the truck cab and subdued him.

No bystanders were hurt in the incident.

The 37-year-old man from Bay Shore, who police identified as Jose Amaya, was arrested and brought to Stony Brook University Hospital for evaluation.

He was charged with menacing a police officer, fourth-degree criminal possession of a controlled substance and fourth-degree criminal possession of a weapon.

Attorney information for the suspect was not immediately available. He was scheduled to be arraigned on Tuesday.
