A police spokeswoman says a second victim has died in the attack on a school in southern Sweden by a knife-wielding man.

Police spokeswoman Maria Randsalu said Thursday that the second victim is a male student, but didn't provide further details. Students fled from the Kronan school in Trollhattan, near Goteborg, Sweden's second-largest city, after the attack in a cafe near the school just after 10 a.m., police said.

Police arrived to find one male teacher already dead and two students, aged 11 and 15, and another male teacher wounded. The second victim was one of those students.
