Yikes — sounds like Jonathan Cheban got far more than a spicy tuna roll during a late night sushi supper at his new Brooklyn restaurant! Kim Kardashian’s bestie stopped by his latest venture, Sushi Couture, for a late night snack when he was attacked by a strange man. Super scary.

Thankfully, Jonathan is OK, but the incident may make him a little more cautious about Instagramming his whereabouts in the future. The entrepreneur and occasional reality star shared a pic of himself enjoying some tasty-looking fruits de mer and gyozas, along with a geotag of his location, and that social media update may have been what alerted the alleged attacker to pay Jonathan this very unwelcome visit.

According to an eyewitness, the man entered the Brooklyn eatery and began yelling at Jonathan. He was screaming, 'Cheban! Cheban! I came here to talk to you!'” the source recalls.

But the menacing tone of the man’s voice wasn’t the only reason patrons and staff were concerned. “His eyes were huge and he had a large pocket knife hanging off his belt — it was really scary,” the witness says, adding, “He looked like a stalker."

Whatever the deal was, Jonathan has some great security to thank for the fact that he got away unharmed. The patron who relayed the series events to E! News reveals the man tried to physically attack Jonathan as he and his entourage attempted to leave the restaurant.

"The security guard had no choice," the witness explains. "He punched the stranger in the face and hustled Jonathan out of there."

Glad you got away OK, Jonathan. And, hey, give that guard a bonus, huh?
