An unidentified man leaped over a barrier and knocked Justin Bieber to the ground outside the Macy's in Manhattan's Herald Square earlier this afternoon. According to TMZ, the man was a member of the singer's security team in plainclothes who jumped into action when the crowd outside the department store became unruly.

The teen idol, who was at the store promoting his new fragrance, was not injured, though witnesses say he appeared to be very "shaken up." Shortly after the incident, Bieber attended a meet-and-greet with fans inside the department store.

This isn't the first time Bieber has been attacked at a public event. Back in May, the singer was egged by audience members at a concert in Sydney, Australia.

Unsurprisingly, the singer's intense fanbase have been expressing their concern and anger about the apparent attack on Twitter. Some fans, who have I.D.'d the jumper as "Tom Peterson," have been especially bloodthirsty. "Tom Petterson better be arrest, not for JUST for attacking Justin, but for suicide, cause i think he knew that 1 belieber would KILL him!," says @gomez_fan_1. Another fan with the handle @LegitBieberLove said "Tom Petterson, I'm about to fucking kill you. Punching a 17 year old kid in the face? Get a life motherfucker."
