Georgy Myakinkin, 31, who works at the airport in the city of St Petersburg in north-western Russia said he had finished his shift and was going home when he remembered he had left his keys at work.
He said: “I returned back to the airport and was just in the section where trains arrive with passengers when I was stopped and asked to remove my belt before going through a scanner. I know the rules and I know that it isn’t necessary here in the pre-flight area to be so strict, and security guards were just being heavy-handed.
“When I refused and told them I wanted to just get my keys, they called police.”
Angry at officers demanding he remove the belt as requested, he had then stripped off everything in front of staff in St Petersburg’s Pulkovo airport, and then walked through the scanner with just his socks on.
