Solange Knowles is sticking by her story about Miami police pulling a weapon on her and her friends over the weekend. A rep for Beyonce’s little sister tells E! News it all started when Solange and two friends were denied entry into a Miami Beach nightclub while carrying a large balloon they were planning to give to a friend the next day. According to the rep, two police officers then approached Solange and her friends when they took the balloon across the street to deflate it. The conversation with the officers apparently started off casual and lighthearted, then one of the officers allegedly pulled out a switchblade and threatened to pop the balloon. Solange says she and her pals thought the gesture was inappropriate, but says they were more disturbed when the officer took out the switchblade a second time and said to them, “I don’t find humor in this, anymore,” then “forcefully” asked them to move.

The singer says she made several calls to report the incident and was told to be prepared to be arrested was not true. A Miami police spokesman told E! News earlier that Solange was being abusive and disruptive. The singer says she never once raised her voice, nor did she do anything illegal. Solange’s rep says the singer is actively filing a report, but has not yet decided on further legal action. A police spokesman says the department may launch an internal investigation.
