The police report does not describe any police officers being injured and doesn't address whether any officers punched Brooks.
Telephone messages for Ramirez and other Barstow police supervisors weren't immediately returned.
Brooks was examined at Barstow Community Hospital before he was taken to a San Bernardino County jail in Rancho Cucamonga, Calif., police said
Jail records show Brooks was being held on $100,000 bail pending a Tuesday court appearance on four felony charges including resisting a police officer with force, willful harm to a police service dog, felony evading arrest and throwing objects from a vehicle.
Earlier Thursday, Brooks was expelled from the state Assembly by a voice vote following a recommendation from a bipartisan panel that met largely behind closed doors. The seven panel members considered a more than 900-page investigative report produced by a Las Vegas lawyer hired as a special counsel.
A coalition of Nevada media outlets is seeking to have the document made public.
Assembly Majority Leader William Horne, D-Las Vegas, called Brooks "potentially dangerous" and said lawmakers didn't feel safe with him in the building.
"This really saddens me," Horne said Friday, after learning of the arrest. "I hope they get Steven the help he clearly needs before he or someone else is hurt or worse."
The arrest was Brooks' third this year.
He was arrested Jan. 19 after being accused of making threats toward legislative colleagues including Assembly Democratic Speaker Marilyn Kirkpatrick. North Las Vegas police said Brooks had a gun and ammunition in his car when he was arrested, but no charges have been filed.
Brooks was hospitalized for five days for a mental evaluation after Las Vegas police were called Jan. 25 to a dispute at his grandmother's house.
Brooks was sworn in at the Legislature on Feb. 4 before he was arrested again Feb. 10 at his estranged wife's home in Las Vegas after police alleged he threw punches and grabbed for the gun of an officer who responded to a domestic dispute. He faces a court hearing in May in Las Vegas on one felony and three lesser charges.
Brooks was denied the purchase of a gun in northern Nevada last month after he was banished from the Legislature.
Posin said at the time that Brooks posed no real threat to anyone.
