MOSCOW, January 6 (RIA Novosti) – A local man was detained in western Russia for putting up for sale six mortar bombs, police in the Russian exclave of Kaliningrad reported.

The projectiles were mementoes from World War II that the suspect found in the area, the police statement reads.

The 29-year-old man, whose name was withheld, successfully tested one bomb by throwing it in the fire.

He then put up the rest for sale for an unspecified sum, only to find out that the buyer was an undercover police agent, according to the report.

The man, who has a criminal record for drug dealing, was detained in mid-December, but the story was not reported earlier.

Illegal arms trafficking carries a prison sentence of up to three years in Russia.

Kaliningrad was the site of a major battle during the war and was captured by the Soviet Union from Nazi Germany.

Last year, regional police busted an arms trafficking ring dealing in World War II-era firearms, which were shipped to customers by post.
