According to police, the man has targeted older people by approaching them and asking for an address. He should then have developed a map on their walkers and then taken their wallets.

In addition to stealing cash, he must also have made withdrawals with the persons' bank cards.

- Aging crimes are of a different nature, but unfortunately they are not uncommon. They usually focus entirely on older people - preferably over eighty years, says police spokesman Stefan Gustafsson.

The man is active in large parts of southern Sweden and now the police are appealing for the public's tips.

Why do you go out with a picture of the suspected offender?

- That's an assessment question. If it is a crime-free person and it happens on a regular basis, we may need to get help from the public, he says.
