_In Touch* has exclusively learned that Jon Gosselin is seeking full custody of daughter Hannah, because he believes she is traumatized by her mother’s alleged harsh behavior toward her.

During a visit with her father on April 23, “She said she didn’t want to go home to her mom [Kate] because she can’t take the cruelty anymore,” an insider exclusively reveals to In Touch. “Hannah was so afraid of her mom that Jon became concerned and called [Berks County, Pennsylvania] Children & Youth Services and filed a report — and he took emergency custody of Hannah” — without a court order.

Not surprisingly, Kate flipped out.

“She showed up at Jon’s house and stood in the street screaming for Hannah to come home, but she wouldn’t leave,” the insider tells In Touch.

“Then she called the cops on Jon and made claims about him,” adds the insider.

Kate (whose rep didn’t respond when asked for comment on this story) took the little girl back home after she spent four days with Jon.

“But Jon will be filing a petition to modify custody, and if he gets it, he’ll be contacting TLC to put a stop to filming [Kate Plus 8],” says the insider. “Hannah doesn’t want to film, but Kate is making her and she’s not the only child who has no interest in being on the show.”

This isn’t the first time Kate’s been accused of abuse. In November 2014, Children & Youth Services launched an investigation into allegations that Kate had been physically and psychologically abusive to one of her sextuplets, Collin. (Investigators ultimately ruled the claims were “unfounded.”)

And in March, court documents from 2010 surfaced showing that Kate had been accused of hitting her kids to the point of leaving marks on their bodies. She had even locked them in their bedrooms to prevent them from using the bathroom at night. “The judge told her that if there was a fire and something happened,” says the insider, “that would be considered manslaughter.”
