McGregor was later released on a $125,000 bond, the Miami Herald reported.
Samuel Rabin Jr., a Miami-based attorney representing McGregor, said the fighter was involved in a "minor altercation involving a cellphone" and would cooperate fully with police, the Herald reported.
The arrest report, which did not identify McGregor by name, said "the victim attempted to take a picture of the defendant with his cell phone" outside a hotel.
"The defendant slapped the victim's phone out of his hand, causing it to fall to the floor. The defendant then stomped on the victim's phone several times, damaging it," the report said, adding that the device was valued at $1,000.
