The entrance of the Bunny Ranch in Mound House was destroyed after a stolen semi-truck was rammed into the building around 3:30 a.m. Thursday morning. 

The suspect, 40-year-old Brian Brandt of Reno, was arrested on scene, just after the crash. He's charged with with assault with a deadly weapon, destruction of property of another, and possession of stolen property.

Terrified employees witnessed the 18-wheeler intentionally backed into the entrance of the Bunny Ranch.

"It sounded like a bomb went off in here," said employee, Jenny Jade. "Everything was all shaking."

"The reaction was 'what do we do,'"said owner, Dennis Hof. "We immediately called 911."

Brandt allegedly stole the big rig from his former employer, Central Transport in Sparks. The company tells us he was angry for being fired in February. Managers found the front door of their facility smashed in Thursday morning and a truck stolen.

Hof says he has no connections to Brandt, but believes he wanted to harm his business for the notoriety. 

"My guess is he knew it would be worldwide news if he rammed his truck into a brothel with 35 hot girls in it that is world famous."

Hof says the suspect was also wearing full body armor. He posted surveillance video of the crash on his Twitter account, @DennisHof. You can watch it below.

The Lyon County Sheriff's Office says the incident was isolated, and that there's no threat to the community.

Hof said no one was hurt, including the five employees, 30 female prostitutes and 10 customers in the building.

The front of the building is destroyed, and estimates damages at $400,000.

They don't know right now if alcohol and/or drugs were involved.Â
