According to Las Vegas police, an altercation occurred at Aria nightclub at 2 a.m. and Derulo "committed battery against two persons."
Emails to Derulo's manager and agent requesting comment were not returned Tuesday.
According to media reports, Derulo, 32 years old, was seen striking at least one person close to an escalator. He was cursed by someone and called him Usher.
Police stated that Derulo did not wish to press charges against him. Derulo was then told by security at the hotel to vacate the premises under a trespass warrant.
Police claimed that no police report was made because the suspects did not wish to be prosecuted.
Since 2009, Derulo has sold millions upon millions of songs and has 11 Platinum singles such as "Wiggle", "Talk Dirty", "Want to Want Me" and "Whatcha Say."
