It was in May this year that two kittens were found cut up in a park in London. Parts of the kittens' fur and skin had also been burned off.
At the scene, the police also found knives, blowtorches and scissors.
Now a teenage boy is sentenced to one year in prison for having killed the cats through "sadistic" torture. According to the prosecutor, the boy had also wanted to kill a person and investigated "how to get away with murder".
In notes on the boy's mobile phone, it was written that "I have killed cats to reduce my desires".
A teenage girl is also charged in the case but the trial against her has not yet begun.
According to BBC, the British police are investigating possible links to a broader international network whose members share videos on the internet of cats being tortured or killed.
