The Olympics is a pretty safe place to be, but in case there's no security around when something bad goes down ... there's a Latvian judo champ wandering the streets ready to spring into action.
Our guy in London met Gasan Eldarov, a weightlifter/fitness model/trainer/judo star from Latvia ... who told us that if he saw a crime being committed, he'd handle things himself.
Gasan explained, "I just break the neck, ya know? No problems."
One small problem ... we can't find any mention of Gasan on any Olympic website.
Maybe we'll need security after all.
