Technology news from Mobile World Congress isn't the only thing coming from Spain this week. Apparently, news of a Spanish hacker has been arrested for stealing gamers' details and blackmailing game company Nintendo.

According to BBC news, a Spanish hacker has been arrested for stealing 4,000 Nintendo gamers information. On top of that, the unnamed individual has also threatened to contact the country's data protection agency, accusing the game company of negligence.

The hacker had leaked some details online when Nintendo did not reply. Authorities said that he planned to release the entire user information on the web, but the hacker was arrested before he got the chance to do so. It was unclear if the data theft was done via Nintendo's computer system or through a third-party.
