After several brawls broke out in a Southern California mall, a rule has been implemented for minors requiring them to wear lanyards that contain their name and a parent's contact information, ABC 7 reported.
The rule goes into effect every day at 5pm.
Video posted to social media showed hundreds of teens and young adults running around the Del Amo Fashion Center in Torrance, participating in violence and assaults.
It took several hours for cops to disperse the crowds. Police say there may have been as many as 1,000 people involved in the melee.
