George Zimmerman has reportedly fled Miami after being told there was a £10,000 bounty on his head.
The unconvicted killer of black teenager Trayvon Martin was enjoying a family break with his girlfriend and her kids recently when he started receiving death threats, TMZ reports.
Angry passerbys are said to have recognised the former neighbourhood watchman - who confronted and shot Martin as he walked through a gated community in Miami, Florida in February 2012 - and started harassing him.
Fearing for his life, he retreated to the hotel only to be followed by the mob, who was seeking justice for Martin's death.
The celebrity news site claims that hotel security was forced to stand guard throughout the rest of the group's short stay.
In July 2013, Zimmerman was found not guilty of murder after claiming he shot the 17-year-old in self-defence after a row ensued between the pair.
Although his acquittal sparked nationwide protests, the 30-year-old, who identifies himself as Hispanic, says only God can judge his actions on that day.
"I know that ultimately, he's the only judge that I have to answer to," he said in an interview broadcast on CNN's New Day programme.
"He knows what happened. I know what happened. So I'd leave it up to him."
In March 2012, before Zimmerman was arrested, the New Black Panther Party posted a video online announcing a $1million reward for the "dead or alive" capture of Zimmerman.
"We're going to force our government to do their job properly, and if they don't we will," a spokesman for the controversial group said at the time.
"So white America, we have given you 400 years to get it right and you still have failed black people. We're not even citizens in this country. We're still third class citizens."
