Chris Brown is allegedly involved in an assault investigation after an incident on the set of his latest music video. A woman has filed a police report for third-degree assault after being kicked off his bus.

TMZ reported Brown was filming a music video Monday night at the Platinum 84 Gentlemen’s Club in Denver. The woman, who was unnamed, was not part of the production but was a guest on the set. The production had rules banning cell phones so no footage would be leaked. 

The woman was “forcibly thrown off Brown's bus after refusing to give up her cell phone,” TMZ reported. She also said her phone was broken while she was removed her from the bus, according to TMZ.

While Brown and several people who work with him are considered "persons of interest," no arrests have been made. The police are still interviewing people and reviewing security footage.

The “Liquor” singer’s newest legal concern comes as another one ended. Last week, Brown was awarded joint custody of his daughter, Royalty. He and her mother, Nia Guzman, spent months in court fighting over custody and child support payments. On Sept. 11, the judge ruled the 1-year-old would spend four days at a time with each parent and Brown would continue to pay $2,500 a month in child support.

Brown also may have some international legal battles coming up. The singer scheduled an Australian tour, but he may not be allowed to play his New Zealand date. Due to his 2009 arrest after assaulting singer Rihanna, Brown was refused entry to the U.K. in June 2010. Because another country denied him entry, New Zealand will not let him in without special permission. “If Chris Brown has been excluded from another country, he will be ineligible to be granted a visa to enter New Zealand unless given a special direction,” a representative for Immigration New Zealand told the NZ Herald. The representative also noted that Brown had not yet applied for a visa.
