An Australian photographer said he was punched by Taylor Swift's father on a wharf on Sydney Harbour early on Tuesday morning.
A police investigation is underway into an alleged assault involving a 71-year-old man and another man on Neutral Bay wharf about 2.30am on Tuesday.
New South Wales Police did not name Swift's father, Scott, who is 71 years of age. The alleged incident happened after the star’s final concert in Sydney.
Local media reported the complainant was an Australian photographer who was waiting for Taylor Swift and her father as they arrived at the Neutral Bay wharf following a late-night cruise on Sydney Harbour.
Taylor Swift was with her father at the time, but had entered a car when the alleged assault occurred, according to state broadcaster ABC.
A spokesperson for Taylor Swift told Rolling Stone two people were acting "aggressively" towards Swift and her entourage when the incident occurred.
"Two individuals were aggressively pushing their way towards Taylor, grabbing at her security personnel, and threatening to throw a female staff member into the water," the spokesperson said in a statement.
The ABC reported the photographer, Ben McDonald, said Swift's entourage used umbrellas to try and prevent him taking photographs and in the alleged altercation Swift's father became involved.
Mr McDonald said media had been waiting to photograph the star as she walked with her entourage from a jetty to two waiting cars.
“There were about four or five security there and at one point, one of the American security started shoving his umbrella into me and my camera and then Taylor got in her car,” McDonald told the AP.
“Someone else came running at me and punched me in the left side of my face. Initially, I thought it was an Australian security that was trying to be the hero of the moment in the front of the Americans, but as it turned out it was her father,” Mr McDonald added.
“In 23 years, I haven’t been assaulted and punched in the chops, particularly by the talent’s dad,” he added.
McDonald claimed there had been no cause for violence.
Taylor Swift left the country on a private jet Tuesday, after more than 600,000 fans saw the Australian leg of her Eras Tour at seven Australian stadium concerts.
