A Denver mom was arrested for attacking a school employee who wasn’t letting her kids off their bus — hitting him with a flurry of punches during a wild, caught-on-camera brawl.

Viral footage viewed more than 1.25 million times on Facebook shows a group of increasingly agitated parents standing behind the yellow bus, as middle schoolers screamed and begged to be let off.

Mom of five Brandi Martin, 32, finally snapped, jumping up into the back of the bus and trying to force her way past a 70-something-year-old employee to get to her kids.

It sparked a wild tussle between the pair, with the male employee in a reflective vest aggressively trying to hold back the mom — who finally landed a series of punches to his head before jumping off the bus.

Martin claimed that the employee had assaulted her, with her holding the back of her head and appearing close to collapsing once off the bus.

But she was the only one arrested — with the school bus driver and aide both placed on administrative leave during an investigation.

The victim sustained “visible injuries” to his face and was taken to Denver Health for treatment after the Sept. 18 fight, police told 9 News.

The employees say they pulled over in between stops to try to address bad behavior and tried to explain to the parents that regulations meant they could not let the kids get off until they were at official stops, according to the reports.

Martin said it was “pretty terrifying seeing my daughter being held against her will and not being able to get to her.”

“What hurts me the most are the screams. I can hear them in my dreams,” she tearfully told the Denver Channel.

“I feel like any mother was going to get on that bus to get their baby.

“I felt like I was fighting for my life and these children.”

Martin has not been charged pending an ongoing investigation, according to the reports.

Denver public schools superintendent Susana Cordova wrote to parents, saying she was “very upset by the way last week’s bus incident was handled.”

“The most upsetting part of the incident to me is hearing our students crying out in distress,” Cordova said in the letter, according to 9 News.
