E! News reports Brown is accused of assaulting a woman at a San Diego nightclub on Saturday evening.
The Anaheim Police Department reportedly received a phone call from a woman alleging that she was pushed by the rapper during his performance at Heat Ultra Lounge at 9:30 p.m. on Sunday night.
The woman did not meet with the police in person regarding the incident and E! caims the investigation is "currently ongoing," and police have sealed the identity of the woman involved in the alleged incident.
Brown has since tweeted, "I didn't do anything." His tweet was later deleted according to E!
Brown is still on probation until next summer. The judge set a preliminary hearing date for July 15 to determine whether they should move forward with a probation-violation charge.
Meanwhile Heat management's Mike Joher of Royal Entertainment gave a statement to E! News in a statement that, based on information gathered from their security, "it is apparent that the alleged incident regarding Chris Brown is false."
Brown "was a complete gentleman and remained professional throughout the entire night," Joher concluded. "Neither I, nor any of the witnesses we spoke to, saw him push or touch anybody."
