Updated at 3:20 p.m. PT, Thursday: Justin Bieber was reportedly shaken up after being knocked to the ground by a man outside a Macy's store in New York City on Thursday.
According to TMZ.com, the man was an undercover policeman.
The website for WABC reported that Bieber was at the store promoting his new fragrance for women when he went outside to greet a large crowd of screaming fans. Bieber reportedly deviated from the planned route, and the crowd became too rowdy. At that point, the policeman -- who was not in uniform -- jumped a barricade to help the teen singing sensation, TMZ reported.
Gossip Cop reported that a man was taken into custody, and the New York City police told The Associated Press that a 47-year-old man was issued a summons for disorderly conduct. That man, according to TMZ, is one of Bieber's security team members. The undercover policeman reportedly cited the security member for grabbing the cop, pulling him away from the singer and refusing to back off after the policeman identified himself.
Bieber's representative told the AP that it was all "a misunderstanding." The singer wasn't injured.
