A source at the scene told The Holly Reporter there was a major police presence in the area, as well as a SWAT vehicle and a helicopter circling above. 

Responding officers encountered the suspect barricaded in his room. Crisis negotiators made contact with the suspect and he willingly surrendered to the police. 

The Beverly Hills Police Department later said it had detained a suspect and will remain on scene to investigate. There was no longer a threat to the public and the roads would open shortly, BHPD said.
