Solange Knowles' business partner Armina Mussa, 24, was stabbed 10 times on Wednesday evening in New Orleans. Mussa is the project director of Knowles' Saint Heron brand and co-owner of NOLA boutique, Exodus Goods. Police have reportedly arrested and booked 26-year-old suspect Arronesia Christophe on charges of attempted second-degree murder. Records filed at Orleans Parish Criminal District Court indicate that Christophe was arrested at the location of the stabbing. According to a report from NOLA.com, the stabbing occurred "outside a home in the 2200 block of N. Derbigny Street" in the St. Roch area of the city. The report also notes that Solange, who was not in the city at the time of the incident, cancelled a Coachella DJ gig to be at Mussa's side:

A representative for Knowles said Friday that the singer had no comment but confirmed that she was not in New Orleans at the time of the incident. Knowles was in Los Angeles where she was scheduled to DJ at an event during the Coachella festival but cancelled and immediately flew back so she could be with Mussa and her family, the rep said.

Knowles attended a hearing for Christophe in magistrate Judge Harry Cantrell's courtroom shortly before 3 p.m. Thursday, sources said. She appeared dressed in a crimson skirt, sneakers and an oversized sweatshirt and was seen talking to a police officer in the hallway before the hearing. She appeared "very concerned", a source said.

Armina Mussa is in critical condition. Arronesia Christophe is jailed at the Orleans Parish Prison on a $50,000 bond.
