The hotel then filed a countersuit against Oakley, alleging that the former National Basketball Association star instigated the fracas and pushed, punched, kicked and bit the officers trying to restrain him while also throwing a bystander's camera in the pool.
The 54-year-old former New York Knicks power forward was detained on July 8 after seeking to add or reduce his bet on a casino table game, according to the Nevada Gaming Control board.
It's not known what game Oakley was playing at The Cosmopolitan, but TMZ reported the incident was captured on surveillance video.
Security at the Cosmopolitan stopped Oakley, with the incident being recorded. He was then taken into custody at 5:30 PM and booked into Clark County Detention Center.
The violation is punishable by up to six years in prison and a maximum fine of $10,000 but Oakley is not expected to serve jail time.
"This is an insignificant matter that will be quickly resolved", a source close to Oakley told TMZ.
The former NBA All-Star played three seasons with the Raptors from 1998 to 2001. He has been estranged from the Knicks family over fights with team owner James Dolan, who threw Oakley out of the Garden in early 2017.
Oakley was charged with misdemeanor assault and trespassing, among other charges. The charges against Oakley were later cleared as part of an agreement, which included banning him from the arena for a year.
