After calling the police to report false gun-related activities at the homes of stars like Justin Bieber and Ashton Kutcher, the person responsible for the "swatting" pranks was arrested last week.

An unnamed juvenile was taken into custody by the Los Angeles Police Department on December 10th in connection with the Hollywood hoaxes.

Back in October, law enforcement rushed to Ashton Kutcher's residence after someone called 911 about an armed home invasion that supposedly left people shot.

Just one week later, a similar call brought police to the Bieb's house, only to find that the call was also a prank. The swatter is alleged to have been involved in other false alarms, causing police to divert their attention from real emergencies.
