A knife-wielding prison inmate stabbed two female police officers in the Belgian city of Liege, stole their service weapons and shot them and a bystander dead in an attack Tuesday that prosecutors fear could be terror-related.Justice Minister Koen Geens said the assailant, who was later killed by police, was on a two-day leave from prison. Geens described him as a repeat offender who had been incarcerated since 2003 and was due for release in two years.The attack happened outside a Liege cafe on Tuesday morning. Liege prosecutors’ spokesman Philippe Dulieu said the man crept up on the two officers from behind carrying a knife and stabbed them several times.“He then took their weapons. He used the weapons on the officers, who died,” Dulieu told reporters. The two police handguns had a total of 17 bullets. Dulieu said the attacker then shot and killed a 22-year-old man in a vehicle that was leaving a parking space outside a nearby high school. He then took two women hostage inside the school. “Liege police intervened. He came out firing at police, wounding a number of them, notably in the legs. He was shot dead,” the spokesman said. Police Chief Christian Beaupere said the slain officers were ages 45 and 53, the latter the mother of twins. Four other officers were wounded in the attack, one of them seriously with a severed femoral artery.
