“We received an emergency call this afternoon (Wednesday) that a child was lying lifeless in an apartment… We could confirm in the apartment that the girl was dead and realized that there was a possibility that she had been killed,” Östergötland police spokesman Tommy Johansson told AFP.
A relative of the girl had called police.
“We brought the father in for questioning before arresting him on suspicion of murder,” he added.
Johansson said he did not have the man’s name or age, and that he did not know whether the girl had suffered visible injuries.
“All I know is that her death was suspicious,” he said, adding that police had secured the area to look for clues.
