Las Vegas police released bodycam footage and 911 calls tied to alleged Manhattan mass shooter Shane Tamura — including video of officers responding to a reported mental health breakdown at his apartment and an arrest at a local casino.

The Las Vegas Metropolitan Police Department released the materials late Tuesday citing “extraordinary circumstances” given the mass shooting event last week. In the wake of the killings, the NYPD said Tamura had a documented mental health history.

Tamura, 27, went on a shooting spree with an AR‑style rifle at the 345 Park Avenue office building, where he killed an NYPD police officer, a security guard and two executives before turning the weapon on himself, police say.

In a September 2023 incident, Tamura refused to leave the Red Rock Casino Resort & Spa, leading to his arrest. He was gambling at the casino and refused to show identification after winning money.

After gathering his belongings and leaving the apartment, Tamura got onto a gurney and was taken away by first responders.

Meanwhile, in another video from May 2023, police pulled Tamura over at a traffic stop for not having a rear license plate on his black BMW sedan. After running his details, police discovered that his license had been canceled, and his registration had expired. They then instructed him to park his car as they were confiscating it. Tamura could be seen apologizing to police and following their instructions.

In a 2022 9/11 call, a family member called police to report that Tamura was threatening to take his own life.

“Did he say how he wanted to hurt himself?” the dispatcher asked.”

“He has a gun,” the woman replied. “He keeps it locked in a backpack.”
