Jon Jones is a scary proposition in the Octagon and he used his terrifying presence to good effect when he confronted vandals defacing property as protests rage across America.
The 32-year-old fighter, who has recently threatened to vacate his light heavyweight title as he feuds with UFC boss Dana White, took to the streets of Albuquerque to protect his city.
In a video uploaded to his Instagram account, Jones forces two teenagers to hand over their cans of spray paint to prevent them from graffitiing anything.
Protests and riots have broken out in the US after the death of black man George Floyd, who died when a white police officer pressed his knee into the 46-year-old's neck for nearly nine minutes.
While the Black Lives Matter campaign has consumed America in recent days, Jones questioned whether some are using the protests as an excuse to wreak havoc rather than affect genuine change.
In Albuquerque on Monday, protests turned violent as police in riot gear turned up to maintain order. People started fires in the streets downtown and shop windows were smashed.
"Is this s**t even about George Floyd anymore?!?" Jones wrote on Instagram in a caption accompanying his video. "Why the f*** are you punk a** teenagers destroying our cities!??
"As a young black man trust me I'm frustrated as well but this is not the way, we are starting to make a bad situation worse.
"If you really got love for your city (505), protect your s**t. All you old heads need to speak up, call your young family members and tell them to come home tonight."
Jones recently tweeted he was giving up his light heavyweight title because of a pay dispute with the UFC.
When one of Jones' 2.3 million Twitter followers suggested he was hurting himself more than the UFC, Jones replied: "I hurt myself every time I walk out there and take a punch to the head and not feel my pay is worth it anymore."
Jones had been eyeing a fight with heavyweight Francis Ngannou, but said the UFC did not want to pay him enough. White said the fighter wanted "crazy" money, citing demands of $US15 million, $20 million and $30 million.
"He can do whatever he wants to do. He can sit out, he can fight, he can whatever," White said on Sunday after an event in Las Vegas.
"Jon Jones can say whatever he wants publicly. It's his God-given right here in America. He can say whatever he wants. And when he's ready to come back and fight, he can."
