Olympian Joshua Booth faces police questioning and the wrath of Australia's Games officials after being arrested during a drunken night spent commiserating a failed rowing campaign at the London Games.
Australian team boss Nick Green said the 21-year old had fainted at the police station where he was taken after being arrested for causing damage to a shopfront.
The Olympic debutant from Melbourne hit his head and was taken to hospital as a precaution, but was released on Thursday morning.
"I assume if they've released him that they've cleared him of any medical issues," Green told reporters in London on Thursday, adding that the team doctor was watching over the athlete.
Green labelled it an "unfortunate incident" and confirmed alcohol had been a factor.
An oarsman in Australia's men's eight which finished competition on Wednesday in sixth place, Booth and other crew members went out at Egham, about 90 minutes southwest of London, towards the Olympic rowing venue at Eton Dorney.
"I was with him (Booth) in the afternoon and haven't seen him since," coxswain Toby Lister told AAP on Thursday, adding he had last seen Booth about 10pm on Wednesday.
Lister said a group of rowers had "a few beers" in the afternoon, post race, and that all members of the rowing squad had been warned by team officials to keep their behaviour in check.
"They just said `you're one of the first boats finishing up so just be respectful and just be mindful of what happens the next couple of days particularly around other crews'," Lister said.
He said he had heard nothing of Booth's arrest.
"We'd all been disappointed. You don't want to go to the Olympics and finish sixth," he said.
No charges have been laid against Booth, who must return to the police station for questioning on Friday, Green said.
Asked if Booth will be the focus of Australian Olympic Commission disciplinary action, Green said he needed more information on the rower's actions before making that decision.
"I won't deal in hypotheticals," he said.
"I'll wait until the information comes and I'll make a decision based on what the information says."
Green said he received a phone call from the police station with information of Booth's arrest about 3.30am (BST) Thursday.
Rowing Australia representatives have declined to comment on the matter.
