Police got involved Sunday afternoon after Peconic Bay Medical Center in Riverhead reported treating a man who said he had been injured in a fight at the South Pointe nightclub in Southampton, Newsday reported. Officers talked to him at the hospital and he later gave a statement to Southampton police.
A spokeswoman for the club said Bieber came to the club at 2:45 a.m. Sunday with a group of about 14 people and "stayed for about an hour dancing, enjoying himself."
"When he was leaving a lot of people followed him outside to take pictures, and I think people were getting a little pushy and shove-y," she told Newsday.
The spokeswoman said nothing happened outside the club or in the parking lot. She said Bieber's security staff "confronted" someone after a rock was thrown at their car.
Bieber, who grew up in Stratford, Ontario, was discovered at 14 through videos posted on YouTube.
