A bizarre murder case involving teenage members of a Satanist cult, is making sensational headlines in Finland.

Teenage Satanism sounds like some new fad dreamed up by bored 16-year-olds over a couple of beers just to annoy their parents. But in Scandanavia, Satanism is becoming less and less of a joke.

In Norway alone during the past couple of years, young Satanists have been suspected, and one or two convicted, of burning down perhaps half a dozen of the nation's oldest and most beautiful churches.

Others with links to the fast-growing neo-Nazi movement have been involved in violent attacks on immigrants and refugees.

Gruesome murders

Now a murder case in neighbouring Finland has cast a new and even more sinister light on the Satanist movement.

Four young people - a 17-year-old girl and three men aged 16 and 23 - have confessed to killing one of their associates. Only a few of their victim's body parts have been found.

Helsinki police are investigating other unsolved murders in the vicinity, including that of a dog which was found dismembered in the same flat as the latest human victim.
