A US mother has been arrested for child abuse after she allegedly beat her daughter and forced her to wear a T-shirt bearing humiliating details.

Melany Joyce Alexander, 30, is accused of beating her middle school daughter with a metal-studded belt before sending her to school with a T-shirt flaunting the child’s failing grades.

The handwritten tee shamed the child for earning Fs in all of her classes and further warned her friends, and any prospective boyfriends, to “back off before I get another good woopin like I got last night.”

According to The Mirror, police documents show the child was beaten with a “leather belt with holes with metal divots”, that left impressions on her arms, neck, chest, back and legs.

The T-shirt also said: “My (days) eating French Fries and being a social butterfly is over because I know why my parents send me to school,” it reads in black ink.

It added that the girl was banned from having any friends until her grades were brought up to Cs or better.

“So unless you are helping me with this goal ... back off!!!” it warns.

A police officer responded to West Hernando Middle School, Florida, last Friday out of concern over the child’s attire.

According to the arrest affidavit, Alexander used “excessive” force by the Department of Children and Families, leading to her arrest.
