Shane Tamura, the gunman who killed four people inside a Manhattan skyscraper before killing himself on Monday, was once arrested at a Las Vegas casino for trespassing.

According to an arrest report cited by multiple news sources, the Las Vegas resident was booked on Sept. 27, 2023 for refusing to exit the Red Rock Casino in Summerlin. The trouble began when Tamura refused to show his ID to collect $5,000 he had won, then refused to leave the casino cage until he got his money, the report read.

According to a police sergeant, Tamura reached out, in an agitated state, to grab the security officer summoned to de-escalate the situation. At that point, the sergeant handcuffed Tamura.

Tamura was held in a security holding cell, where he eventually relented and provided officers with his name and date of birth after being told he could be arrested.

The officers then escorted him outside to the parking lot and informed him that he was trespassed (banned from entering the property).

“Instead of leaving property, Shane leaned on the patrol vehicle and threw his ID card on the hood,” the report stated. “Shane was given back his ID and told to leave the property or he will be arrested. Shane still refused to leave and asked how he will get his money.”

Officers arrested him for trespassing and booked him into the Clark County Detention Center. Tamura was released from custody a few hours after his arrest. Two months later, prosecutors dropped the charges, citing the triviality of the crime, which was a low-level misdemeanor.

Tamura was also cited, though not arrested, in May 2024 for driving without a license and registration, KLAS-TV/Las Vegas reported.

Las Vegas police are helping the NYPD with its investigation into Tamura, who lived in Las Vegas and drove cross-country to reach New York.

A spokesperson for Horseshoe Las Vegas said on Tuesday that Tamura worked as a surveillance employee for the casino resort.
