Nyjah Huston jumped a guy at a house party and beat the man's face so viciously he needed surgery to fix a broken nose ... this according to a new lawsuit.
According to legal docs, obtained by TMZ, Ryan Sheehy claims he was at a February 12, 2017 house party in Los Angeles when Nyjah jumped him and started beating the hell outta his face.
In the docs, Ryan claims the pro skateboarder's attack left him with a broken nose, which required reconstructive surgery, and a cut above his left eye, which required stitches and left a noticeable disfigurement.
