"We consider such reports to be a provocation against Interior Ministry servicemen," Colonel Vasily Panchenkov said.
He said Polish reporters might have confused the Interior Ministry's Vityaz Special Forces detachment, stationed in the Moscow Region, with the private Vityaz bodyguard-training center.
Panchenkov said Polish reporters might have been provided with the false and unverified information from interested parties, given the controversy surrounding Litvinenko's death.
Litvinenko, an outspoken Kremlin critic with close ties to exiled oligarch Boris Berezovsky, defected in 2000 and received a British passport shortly before his death in London in November.
Doctors said a lethal dose of radioactive polonium-210 was found in his body.
