A Las Vegas hotel is under fire following a run-in with Meek Mill, who claims the staff discriminated against him.

According to TMZ, the Philadelphia rapper, whose name is Robert Rihmeek Williams, was in Sin City to attend a DJ Mustard day concert at the Marquee Dayclub on Saturday. The security team at The Cosmopolitan Hotel in Las Vegas reportedly prevented him from entering the building.

“If you come from our culture you should never step foot in the cosmopolitan hotel they just really racist as hell …. something really has to be done in Las Vegas what they doing to black people,” Meek Mill wrote in a tweet.

Videos captured of the encounter showed members of Mill's entourage interact with the security team. The 32-year-old is seen in the backseat of an SUV speaking to hotel staff members.

A lawyer representing Williams has demanded the hotel apologize for treating the rapper and justice reform activist as a criminal.

“We have learned the Cosmopolitan maintains a list of African American recording artists who should be denied access for no other reason than their culture and skin color,” lawyer Joe Tacopina wrote in a letter obtained by TMZ.

Local news source News 3 Las Vegas reports the hotel does not comment on issues of this nature. In a statement provided to News 3, The Cosmopolitan refused to offer an update on the incident involving Mill.

“As a matter of company policy, we do not comment on legal matters," the statement read. "Our guests’ safety and security always remains our top priority.”

In the meantime, Williams wrote on Twitter he will seek legal action.
