"Officers seized a bayonet from a backpack prepared for school, as well as a meat cleaver from the apartment," the statement read. "Proceedings involving the 13-year-old are currently underway, in the presence of a parent." Cybercrime officers are also involved in the case, the statement said, adding that other security services have been informed. Suspect ‘killed cats’ Police detained the boy after a tip-off from abroad via the force’s international cooperation bureau. The boy, meanwhile, admitted he had killed a number of cats over the summer recess and had shown police where their bodies were buried, officers said.
