Police on Wednesday were looking into the motives of a 86-year-old man who was arrested on suspicion of shooting into a hospital in Saitama Prefecture and holing himself up in a nearby post office with two female hostages the previous day.

¡°I wanted to talk to someone from the post office,¡± suspect Tsuneo Suzuki was quoted as saying, adding that the hostages were taken at random and that he wanted to meet a specific person there.

Suzuki said that he had a grudge against the post office and was dissatisfied with the way he was treated after a motorcycle accident involving a post office worker in Saitama Prefecture, where the incident took place, police sources said.
