A police officer was fatally stabbed at a police box in Sendai early Wednesday by a man who said he had come to hand over some lost cash, the police said. The attacker was shot to death by another officer.

The incident occurred at around 4 a.m. at the Higashi-Sendai police box in the Miyagi Prefecture capital, the police said.

Hiroaki Seino, a 33-year-old senior officer, was pronounced dead after being taken to a hospital. A 47-year-old police sergeant, who was in a separate room, heard someone shouting angrily and found Seino and the attacker drenched in blood.
