A gunman launched an attack near a casino in Reno, Nevada, on Monday morning, injuring several individuals before being arrested, according to the police.

Reno police spokesperson, Chris Johnson, mentioned that the current medical conditions of those injured at the Grand Sierra Resort are not yet known. He also noted that the shooter is receiving medical attention at a hospital.

The shooting was reported around 7:30 a.m. Monday outside in the valet area, Johnson said.

A spokesperson with the Washoe County Sheriff’s Department said an officer was involved in the shooting.

Reno police warned residents to stay out of the area. Multiple emergency vehicles, including several ambulances, responded outside the casino.

The Grand Sierra Resort, boasting the largest casino floor in northern Nevada, is situated a few blocks from the Reno-Tahoe International Airport. It is one of the city’s tallest structures, offering nearly 2,000 hotel rooms.

“My heart breaks for the victims, their families, and our entire community. Reno is strong – but we are not immune to the epidemic of gun violence gripping this nation,” city council member Devon Reese said in a social media post.
