A suspect in a 3.5 billion yen jewelry robbery in Tokyo's Ginza district in March has been arrested in Paris, the Press Association reported Tuesday.

The British news agency said the arrest came to light during the trial of a suspect in connection with a jewelry store robbery in London.

The revelation came during the conviction of Nebojsa Denic, a 34-year-old Kosovar Serb who was found guilty Tuesday of taking part in a robbery targeting Graff jewelers in London in May last year. Diamonds worth some £23 million were stolen in the London heist.

The court in London was told that Denic held back staff with a gun, while his accomplice -- known as Marco from Montenegro -- made off with the gems.
