WARSAW, Poland — A teenager allegedly attacked three employees at a primary school in Poland Thursday, killing one, authorities said. Thursday’s attack occurred around 9 a.m. in Leszczydół-Nowiny, roughly 50 kilometres (30 miles) northeast of Warsaw. The suspect, a 15-year-old former student, attacked the school’s principal, a custodian and a teacher with a sharp object. The teenager was subdued by the school’s principal and taken into custody, according to Polish news agency PAP. The custodian, a 37-year-old woman, died. The violence occurred a day after a 19-year-old student at a vocational school in northern Poland attacked fellow students, teachers and passersby with a sharp object, wounding eight people before fleeing and being taken into custody nearby.
