A black-and-white cat was found hanging from a tree in a residential area on March 10th, reported tabloid Expressen GT.
Two days later locals found a yellow-and-white male cat with a ripped open stomach. His name was Birk. Someone had drawn a smiley face on a yellow Post-it note and stuck it to his body.
Locals posted warning notes in the area urging neighbours to keep their cats indoors. Several told Sweden's TV4 news that they were scared to let their children out on their own, knowing that a "psychopath" was in the area.
A third murdered cat, also with a ripped open stomach, was found by the entrance of an apartment building on March 21st.
Locals complained that the police were not taking their concerns seriously.
"This has received so much publicity now that they have to do something but previously they did not care about our reports," Birk's owner Karl Rosenqvist told GT.
Ulf Åsgård, a psychiatrist and an expert on criminal profiles, said the unknown cat torturer could be dangerous to people as well as animals.
Concerned Högsbo residents organized searches to find the culprit.
The arrested man, who is in his thirties, is suspected on reasonable grounds.
