The Los Angeles Police have arrested a knife-wielding man who was seen outside of singer Ariana Grande’s Hollywood Hills home.

Aaron Brown, 23, allegedly arrived at the pop star’s home around 2am on Friday and demanded to see the songstress, 28, according to TMZ. When security brushed him off he brandished a knife, prompting them to call LAPD.

Brown was hit with a felony brandishing charge, the report said.

It is unclear if Grande was home during her security team’s encounter with Brown. But the singer has been granted a temporary restraining order against the suspect.

A judge will determine if the order needs to be extended at an upcoming hearing.

Last May Grande and mother Joan were granted five-year restraining orders against a stalker named Fidel Henriquez. Police arrested him after he snuck past her security to leave a love note at her door.
