Rapper charged with assaulting police officer while in underwear

US rapper Lil Nas X has pleaded not guilty after being charged with assaulting a police officer while walking in downtown Los Angeles in his underwear.

The musician, real name Montero Lamar Hill, was taken to hospital and arrested after police responded to reports of a naked man shortly before 6am on Thursday. The district attorney's office said on Monday that Lil Nas X faces three counts of battery with injury on a police officer and one count of resisting an executive officer.

He was being held on a $75,000 (£55,457) bail, conditional on attending drug treatment. It is not immediately clear whether he had posted it and been released yet.

He is set to return to court on 15 September for his next pre-trial hearing. During the hearing on Monday, Hill's lawyer Christy O'Connor told the judge he had led a "remarkable" life, adding: "Assuming the allegations here are true, this is an absolute aberration in this person's life.

"Nothing like this has ever happened to him." A law enforcement source told Sky's US partner network, NBC News, on Thursday that the Old Town Road and Industry Baby hitmaker punched an officer twice in the face during the encounter. The source added officers were unsure whether he was on any substances or in mental distress.

In the videos, Hill tells a driver to "come to the party" in one clip and in another tells the person: "Didn't I tell you to put the phone down?" "Uh oh, someone's going to have to pay for that," Hill says as he continues to walk away.

In some clips, Hill struts as if he's on a catwalk, posing for onlookers, and at one point he places an orange traffic cone on his head..
