Songz -Tremaine Aldon Neverson, 37, was in Las Vegas over the weekend to celebrate his birthday.

On Sunday November 28, the Las Vegas Metropolitan Police Department received “a report of a sexual assault incident alleged to have occurred at a hotel in the 3700 block of South Las Vegas Boulevard,” a spokesperson for the department said in a statement to PEOPLE.

The reported incident involved the singer, whose legal name is Tremaine Neverson, according to police. The department’s sex crimes division is investigating.

“Neverson is cooperating with the investigation. At this time, no arrests have been made,” the statement concluded.

Last year, Songz was forced to deny another sexual misconduct allegation after a woman named Aliza described an encounter with the singer when she said he took away her phone and purse and wouldn’t let her leave a hotel room.

“I kept asking, like, ‘When can I leave, what time is it?’ ” Aliza said. “And he just, like, wouldn’t answer, he would just f——- ignore me. And I’m like, ‘Okay.’ And then he was like, ‘You can leave when I go to my flight,’ and I was like, ”Kay, when’s that?’ Wouldn’t tell me.”

Aliza also claimed that, during the otherwise consensual encounter, Songz urinated on her without her consent and that she “didn’t know what was happening, he just did it.

Songz addressed the claims on social media, writing that the accusation is “convenient” for someone who seeks “to destroy someone’s life.”I usually stay quiet on this but I feel that in many ways the movement to fight for the women who actually have suffered harassment and abuse on various levels, has been hijacked by those who find it convenient for themselves to come up as they seek to destroy someone’s life,” he tweeted.

In 2017, actress Keke Palmer alleged that Songz used “sexual intimidation” on her in order to make her appear in a music video.

After Songz released the video for his remix with Fabolous to the Travis Scott and Young Thug song “Pick Up the Phone” at the time, Palmer claimed she didn’t authorize the singer to include her cameo.

“This is preposterous. How am I in this video Trey? After you found me in a closet HIDING because I was so afraid of anymore conflict,” the Scream Queens actress, now 28, wrote in a lengthy Instagram post at the time. “Literally my last option was to hide because you all would not listen when I said I did not want to be in the video the FIRST time. Just cause you give someone food and alcohol and throw in a little sexual intimidation doesn’t mean they will buckle.”

Palmer claimed that although the two have known each other for many years, Songz “secretly filmed” her and “put me in the video against my wishes.”

Songz appeared to address the situation on Twitter and Instagram at the time

“Babygirl buggin. Point blank period. Got my number, coulda called, saw the cameras and the lights, heard action,” he wrote on Twitter, later following up, “I don’t do this twitter s—, girl you know me and got my number f— outta here.”On Instagram, the singer wrote, in part, “So sorry for those that believe everything without knowing anything. However, I cannot devote my life to responding to, or clearing up every side of every story you hear about me, when would I actually live? I know my character, I know my truth, I know my heart. God does too.”

Juma said he overreacted after seeing a picture of Vanessa took with Nigerian rapper Ice Prince. He described the 2017 photos as ‘Intimidating’ in an interview with Dozen Selection.

He said “Vanessa was traveling and I was looking at Instagram pictures, I saw pictures with Ice Prince, and there were people I was sitting with, they ask me now what pictures these people are taking. The future. Then there came the Trey songz stuff. So I sent a text, what is this, delete. She asked me whats wrong with the picture I’m performing. I told her the picture is not cool. So I was paranoid and that caused a lot of controversy. Out of envy and in the heat of anger I told her to find another boyfriend. To be honest I saw him a lot and it wasn’t right. So that photo was the source of our lack of trust. We went nine months without talking at all. I was with Vanessa for 6 years. I will say that my experience with Vanessa has shaped me in a lot more ways than any other. I also fought hard not to lose and I was badly hurt. And to get to the point I took another step that we had found impossible. And anyone who gets the chance to be involved with Vanessa will be a very lucky man. She is a very beautiful and smart woman”.
