One of the US swimmers caught up in a scandal over a made-up robbery at the Olympics says that he cannot explain team-mate Ryan Lochte's actions.

Gunnar Bentz was one of two swimmers who were pulled off a flight in Rio de Janeiro and questioned by police.

He apologised in a statement released by the University of Georgia.

The International Olympic Committee (IOC) has set up a disciplinary commission to investigate the incident and the four athletes' behaviour.

Mr Lochte had claimed that he and a group of fellow US swimmers had been robbed at a petrol station.

But CCTV footage contradicted that story, showing the men had vandalised the petrol station.

Mr Bentz's account of the incident stressed that he was a witness, not a suspect. He said he had never made a false statement "to anyone at any time".

He and the other Team USA swimmers Ryan Lochte, Jimmy Feigen and Jack Conger were in a taxi on the way back to the Olympic Village at about 06:00

They pulled in to a shop to use the toilet but as there was none, they "foolishly" relieved themselves behind some bushes

He did not see anyone breaking open a locked door at the back of the building

Mr Lochte pulled a metal advertisement in a frame to the ground, but Mr Conger said he was "unsure why"

When the swimmers returned to the taxi, two men who Mr Bentz thought were security guards told them to exit the car

The first time a gun was drawn was when Mr Conger and Mr Feigen were walking away from the car - all the swimmers were told to sit on the pavement

Mr Lochte "stood up and began to yell at the guards" and Mr Bentz "cannot speak to his actions"

A passer-by helped translate from Portuguese to English and with his help the swimmers understood that they should pay money if they wished to leave

They handed the guards about $50 (£38) in a mix of US and Brazilian currency, and then they left

Mr Bentz apologised and said: "I regret this situation has drawn attention away from the Olympics, which have been hosted so incredibly well by Brazil and its citizens.

"Without question, I am taking away a valuable life lesson from this situation. In everything I do, I am representing my family, my country and my school. I will not take that responsibility lightly."

Who are the swimmers?

Lochte is one of the most successful swimmers in history, with 12 Olympic medals, and he once had his own reality television show in the US. In Rio, he swam in two events, winning gold in the 4x200m freestyle relay along with Conger.

Feigen won gold in the 4x100m freestyle relay.

Bentz competed in the 4x200m preliminaries, but not the final. He still received a gold medal after the US team's win.
