A Brooklyn mother — arrested for jumping into a fight between her teen daughter and her alleged bully — was protecting her child after school officials dropped the ball twice, according to an $8.5 million notice of claim.

Tameekah Douglas-Stanbury is facing up to a year behind bars for assaulting Renee Tenpow’s 13-year-old daughter during a Feb. 15 fight in the schoolyard of Roy H. Mann Middle School.

Two witnesses recorded the fight on their cell phones.

“Ms. Douglas did what any good mother in her situation would have done — what the school should have done and did not do — stopped the attack on her daughter,” said Cary London, Douglas-Stanbury’s attorney.

Douglas-Stanbury’s 13-year-old daughter was involved in two brawls on school grounds with Tenpow’s daughter that were rooted in bullying, she says.

London filed the multimillion-dollar notice of claim — the first step to filing a lawsuit against the city and the Department of Education — earlier this week for failing to protect Douglas-Stanbury’s daughter on Jan. 26 and Feb. 15.

The fights and ongoing bullying have caused Douglas-Stanbury’s daughter to “fear for her life and fearful of possible retribution” by Tenpow’s daughter and others, according to the notice of claim.

“School staff are trained on the robust protocols in place that ensure any allegations of bullying are swiftly reported, investigated and addressed, and these incidents are always treated seriously,” said Miranda Barbot, a spokeswoman with the Education Department.
