A 16-year-old girl was arrested Tuesday on suspicion of killing her police officer father with an ax in their home in Kyotanabe, Kyoto Prefecture, police said.

Police quoted the girl, a vocational school student, as saying, “I killed my dad because I did not like him.”

The 45-year-old man was found in his bed early Tuesday with ax wounds to his neck.

“My husband killed himself by cutting his neck with an ax,” the officer’s wife told police over the phone at around 4:40 a.m.

But after officers arrived at the scene, the girl admitted killing him and was placed under arrest, the police said.

The family members’ names are being withheld because the suspect is a minor.

An autopsy was planned to confirm the cause of death, the police said.

The girl allegedly killed her father by chopping him in the right side of the neck early Tuesday while he was apparently asleep in the bedroom.

The ax had a blade about 30 cm long, the police said.

The bloodstained ax was found in the living room on the first floor, they said.

When the police arrived, the girl, dazed and covered in blood, was found in the living room with her mother and 19-year-old sister. The mother and sister were sleeping at the time of the attack and were woken by the girl afterward, the police said.

The officer, who joined the Kyoto Prefectural Police in 1981, lived with his wife and two daughters. He was off Monday and scheduled to work a day shift starting at 9 a.m. Tuesday, the police said.

“He was an excellent officer,” said Toshiaki Okano, deputy chief of Minami Police Station, where the officer worked. “I never heard that he had any troubles.”
