The long-time persecutor of Ariana Grande has been put behind bars again after entering the singer's house in Montecito, California, on her 29th birthday, according to TMZ.

Aharon Brown - who has repeatedly violated Grande restraining orders in the past - was arrested Sunday after entering the singer's home while she was not there, a source told the news site.

Brown was also arrested in September 2021 after appearing at the home of a pop star in Los Angeles with a large knife, shouting at Grande and her assured "I will kill you and him".

"I fear for my safety and that of my family," the singer told the Los Angeles Supreme Court, seeking a restraining order against Brown. "I'm afraid that in the absence of a restraining order, Mr Brown will continue to come to my house and try to physically harm me or kill me or my family members."

The restraining order was issued against Brown, but according to TMZ he violated the order recently when he appeared at Grande's house to try to get closer to the star again.

Brown was charged with harassment, theft, damage to power lines, violation of a court order and obstruction, for which he pleaded not guilty. Brown has been in custody since Tuesday.
