A man who was reportedly armed blocked traffic going both ways on the Hoover Dam near Las Vegas, eventually getting arrested on the Arizona side, the Nevada Highway Patrol said.

Officers from the Arizona Highway Patrol, as well as Lake Mead, Boulder City and Las Vegas police all responded to the scene, according to local media.

One of them said “Mr. President release the reports,” according to a witness quoted by KLAS.

The suspect eventually drove over the bridge into Arizona, where he was arrested “without incident,” the Nevada Highway Patrol said.

Traffic on Highway 93 was closed in both directions until around 1:30 pm local time.
