Erick Franceschini, 31, of Milford, Conn., is suing Alston and the Perfection Gentleman's Club in Queens for an unspecified amount of damages, the New York Daily News reported Wednesday.
The suit alleges Alston smashed Franceschini with a beer bottle during an altercation that began inside the club and spilled out onto the street.
"My client had 12 staples in his head," Franceschini's attorney, John Rapaway said. "He suffered a concussion."
His client filed a police report, Rapaway said, but Alston was not arrested.
Police sources confirmed the filing of an assault complaint against Alston, but said it was sealed and they would not release any additional information, the New York Post reported.
