Sylvester Stallone claims his groin was almost torn off in psychiatric ward attack

Sylvester Stallone claims he was sequestered in a psychiatric ward, where another patient tried to tear out his groin.

In his upcoming memoir, “The Steps,” out Sept. 29, Stallone recounted his traumatic childhood and adolescence.

The “Rocky” star told The New York Times in a profile published Saturday that he attended a high school that would punish teenage students who misbehaved by putting them in “a place called Park Lodge or Snake Pit.”

“From the outside it looked like a big old Tudor house from the 1920s, and then you walk in and you get into the heart of the madness,” he recalls. “The smell, the filth, the people running around naked, clawing, hands tied, drooling. That’s what they thought would impress you into never breaking the rules again.”

Stallone said he was there for two weeks and was attacked by a “guy named Jay Bird.”

“He was tall, hairless, always naked, with rotten teeth,” the actor explained. “They called him Jay Bird because he was always naked as a jaybird. And I go into the bathroom on my way to the food hall, and he comes in and walks around me and he rips my throat out and he gets in my pants and grabs my groin.”

Stallone alleged that two guards ran in and started “beating him (Bird) with razor straps.”

When he returned to school, the “Rambo” star said the principal asked him if he had learned his lesson.

“I said, ‘I learned a lot more than this lesson. A much better lesson: You can’t break me,'” he shared. “So when I got to New York and everything that followed, I always felt unbreakable in that way. My heart could be broken, like any human being, but I’m talking about willpower.”

The New York Times contacted Stallone’s high school and a spokesperson responded that while they had not read the book, they respected the star’s “right to tell his story in his own way” and apologized “for any trauma he remembers experiencing.”

Stallone also reveals in this wide-ranging profile that his mother was not a caring figure and his father was unpredictable and violent.

He also admitted to abusing steroids and suffering from bulimia while preparing for 1982’s “Rocky III.”

“Then it became an obsession,” he said, referring to the way he had arranged his body to fit the “Rambo” and “Rocky” franchises.
