USA today published an interesting piece on the Lochte incident. They had a reporter go to the gas station and also talked to the witness who stepped in and translated.

It also has extra video images that shown their act of 'vandalism'. They basically tore down a loose hanging advertising poster from a wall. It also confirms they didn't trash the bathroom in fact none of them even went anywhere close to the bathroom.
The witness also had an interesting quote that the police chief told him that a drama might've ensued had he not stepped in.
“It was also so fast, and what I wanted was to resolve the situation,” says Deluz, who days later talked to police. “If it hadn't been for wanting to resolve that, if I hadn't involved myself, I thought – the police chief told me, ‘Man, if you hadn't gone there in that moment, a tragedy could have occurred.’ ”
A Brazilian judge also says that the actions by the security guards can be interpreted as robbery.
"If they only asked for the amount of the damage, it may not be a robbery," Damasceno said in a message to USA TODAY Sports. "But if the amount taken is higher than the value of the damages, with the use of a weapon by the 'security,' this is robbery."
Damasceno added that even if someone has the right to receive compensation, that does not mean they can determine the amount on their own and take actions such as drawing guns to collect. Brazilian law rarely allows for a person to obtain such a payment through the use of their own force – such disputes should be mediated by the state, he said.
Lochte might have lied and overexaggerated his story but same can surely be said about Brazil authorities
