Danish police said on Thursday they had arrested 135 people in a large-scale operation on suspicion of laundering money defrauded from elderly people.
The money was defrauded by contacting elderly people and convincing them to transfer money from their bank accounts or provide personal banking information.
Those arrested were not the organisers of the scam but what the police call "mules" who allow their bank accounts to be used to launder the cash, said Torben Svarrer, chief of the police's special crime unit.
