Disturbing details in the alleged, ongoing rape of a child at the hands of Jelani Maraj — Nicki Minaj’s brother — have emerged.

According to Page Six, the victim’s 10-year-old brother recently took the stand during the trial. He informed those in the courtroom that in 2015 he was looking for his then 11-year-old sister after having broken a pencil when he found her and their stepfather (Maraj) in the basement.

He says his sister’s pants were “around her ankles” when he discovered them.

“I saw his underwear close to his knees … I thought it wasn’t right,” the boy said while on the stand. “It looked weird to me, so I ran upstairs.”

After the alleged rape in the basement, the boy says he was approached by Maraj and then physically assaulted. He said he was slapped 10 times after he was asked if he saw anything in the basement.

The 10-year-old also says Maraj threatened to take his mother, Jacqueline Robinson, away from him.

“He asked me if I had seen anything,” he said. “I said, ‘Yes.’ He slapped me on the cheek … Jelani said I wouldn’t see her again if I told on him. His face was kind of mad.”

The defense, which previously argued that Robinson was behind a $25 million extortion plot against Maraj’s famous sister, attempted to lessen the 10-year-old’s defense by getting the child to confess that it was dark when he entered into the basement.

At some point in the trial, Minaj is expected to testify on Maraj’s behalf.
