Swimmer Ryan Lochte: 'It was my fault'

US swimmer Ryan Lochte has apologised to the people of Brazil after "over-exaggerating" claims he was robbed at gunpoint while at the Rio Olympics.

Mr Lochte had claimed that he and a group of three other US swimmers were robbed at a petrol station, but CCTV footage contradicted that story, showing the men had vandalised it.
