A teenage girl’s brutal attack on her mother has been linked to an obsession with fictional horror figure Slender Man.

An Ohio mom, who was stabbed by her 13-year-old daughter in the kitchen of their home, has told how her child assaulted her after the girl became obsessed with the fictional character.

“I came home one night from work and she was in the kitchen waiting for me and she was wearing a mask, a white mask,” the mom told local news station WLWT.

The mother suffered multiple minor injuries, including a puncture wound on her back. “She was someone else during the attack,” she said.

The allegations came to light after two Wisconsin adolescents were charged with the attempted murder of a 12-year-old as a sacrifice to the online demon.

Prosecutors allege that Anissa Weier and her friend Morgan Geyster, both 12, stabbed a friend 19 times and left her to die.

One of the wounds came within a millimeter of piercing a major artery near her heart.

Police say the girls told detectives they wanted to murder the girl after reading tales about Slender Man on the horror website CreepyPasta.

The victim managed to crawl to a nearby road, where a cyclist found her lying on the footpath. The injured girl left the hospital last week.

Slender Man, the creation of paranormal enthusiasts, is said to be a lanky, faceless creature in a suit who terrorizes and kidnaps children.

It is believed the spooky figure was invented in a Photoshop contest on the Something Awful forums in 2009 and became the subject of online paranormal fan fiction.

The mother who was assaulted has pleaded with parents to monitor the behavior and reading material of their children.

“We found things that she had written and she made references to Slender Man. She also made references to killing,” the mother told WLWT.

The girl is currently in a juvenile detention center.
