This was the story as I remember it. A bochur from a prominent Lakewood family flew back from Eretz Yisroel to America with a stopover in Russia. He had a few bullets in his suitcase that he got from an Israeli soldier, and he was bringing them back as a souvenir, completely not realizing the significance of them. He was arrested in Russia for smuggling ammunition, and IIRC, he spent about 3 months in jail until they were able to secure his release.
