2 female teachers killed at high school in Sweden, student arrested

Two teachers were killed by a student at a high school in southern Sweden, police said Tuesday. The student, 18, was arrested at the scene on Monday in Malmo, Sweden's third-largest city. The victims were two female teachers in their 50s, police said.

The suspect wasn't previously known to the police and had no criminal record and police didn't disclose how the teachers were killed. A motive hasn't been established.

"For now it is far too early to comment on that," Malmo Police Chief Petra Stenkula told a news conference.
