The father of a woman whose body was found in her former boyfriend's house near Tokyo, has expressed anger over how the police handled the case.



Police found a bag containing a partially skeletonized body of the 20-year-old woman on Wednesday. Her former boyfriend, Shirai Hideyuki, was arrested on Saturday on suspicion of abandoning a corpse.



The woman, Okazaki Asahi, had been missing since December, after complaining of being stalked by Shirai.



Her father, Okazaki Tetsuya, visited a police station in Kawasaki City on Saturday, along with dozens of the woman's friends and others to demand an explanation.



Okazaki told reporters at the police station that he was shocked when he saw his daughter's body.



He said police explained how they responded to the stalker complaint as well as the family's request for an investigation after she had gone missing.



Okazaki claimed everything the officers said was false, and that he believes his daughter died because the investigation was flawed. He said he will never forgive the police.



Okazaki said he will demand that police hold an open session with him and his daughter's acquaintances to get the facts straight.



Police say they took appropriate measures when the woman consulted them, by checking what she wanted them to do. They say they will study whether their response was appropriate.
