A trial has commenced in Kilkis for a 45-year-old Norwegian man accused of murdering a 32-year-old Greek police officer and injuring his friend during a dispute at a bar in Thessaloniki last December. Authorities allege the suspect acted with intent while in a calm mental state, rejecting his claims of being intoxicated. The incident escalated after an argument over a trivial matter, leading to the officer’s fatal stabbing as he attempted to intervene.
