A video shows an unknown man on the floor of FYE on Friday after being taken down by security guards.
The cops immediately shut down the signing and cleared out the entire FYE after the incident.
Big Sean hit up Twitter and claimed the man was patient from a mental hospital who had just been released.
“Look I never comment on this type of s##t, but they can’t do me dirty and say a fan smacked me or no s##tblike that,” he wrote. “Some guy waited in line in the cold since 10am, bought my CD, when I signed his CD n (sic) shook his hand he TRIED to hit me off guard.”
“I wanted to keep the signing going but the store shut it down. Sorry it got ruined for the rest of the real fans.”
