A suspect who allegedly placed fake 911 calls regarding shots being fired at the homes of both Justin Bieber and Ashton Kutcher was arrested earlier this month and has since been released.

The person responsible is a juvenile and police have not released a name, saying only that he lives in the Southern California area. They are currently investigating whether this could be the same person who had police called to the homes of Miley Cyrus and Simon Cowell earlier this year.

The calls concerned multiple people being shot at Kutcher’s home and shots fired at Bieber’s, and were made electronically. Luckily, neither star was home at the time. Investigators have not said whether charges will be filed.

“The swatting practice is extremely dangerous and places first responders and citizens in harm’s way,” police said in a statement.
