Australian Olympic rower Joshua Booth is set to apologise to the owners of a shop he allegedly damaged during a night out.

Deputy chef de mission Chris Fydler told reporters: "We have been working with the local police in that area as well as the shop owners where damage was done.

"We are working through a process at the moment of formally, Josh formally apologising to the shop owners for the damage he caused.

"We've had assessments of that damage and Josh will be paying these shop owners to repair that damage. The amount is approximately £1400 in total to repair that damage."

The 21-year-old was detained in Egham on Thursday morning, and then suffered minor injuries when he fainted and fell in police custody.

Fydler said the Australian mission expected a higher standard of behaviour from its athletes.

"This has been an embarrassing situation not just for rowing but for us as well. We expect a much higher standard of behaviour from all of our athletes and we'll certainly be reminding the section managers, as various sports start to complete, that a level of behaviour is expected of their athletes," he said.

Booth was in the Australian men's eight that finished sixth in their final on August 1.
