MOSCOW, April 11 - RAPSI. Finland’s Interior Minister Paivi Rasanen has apologized to Russian President Vladimir Putin after he was erroneously put on a secret blacklist of people with connections to criminal activity, Finnish media reported.

MTV3 reported Wednesday that Putin’s name had been put on the criminal register due to his contact with Russian biker club Night Wolves. After the mistake was discovered, his name was quickly removed.

“I wish to extend Russia's President Vladimir Putin my sincere apologies for the incorrect registry entry,” the Finnish TV station quoted Rasanen as saying in a statement.

She also pledged the matter would be “thoroughly investigated.”

Putin is known for his support to Night Wolves. When the motorcycle club was established in 1989, its members at first labeled it “a motorgang.” Later Night Wolves cut any associations with outlaw activities, especially since 2009, when Putin, then Russian premier, first visited the club.

Later, the president's spokesman Dmitry Peskov in a statement to the Kommersant-FM radio said that Putin treated the occasion in good spirit, and no official diplomatic response will be issued.
