Police in California have arrested two men who they say they left a Target security guard with a broken arm after a fight broke out over their refusal to wear masks.

Phillip Hamilton, 31, and Paul Hamilton, 29, were not wearing face coverings when they entered the store in the 5700 block of Sepulveda Boulevard in the Van Nuys neighborhood of Los Angeles at around 10.20 a.m. local time on May 1, the Los Angeles Police Department said in a news release.

Store employees confronted the pair about not wearing masks, police said. They refused to wear masks and as they were being escorted out of the store, a fight broke out.
