OSAKA — Mamoru Takuma, who was arrested in the June 8 slaying of eight schoolchildren in Osaka Prefecture, has written an apology letter but was pressured into doing so by police, his lawyer claimed Friday.

Lawyer Eiichi Okamoto said Takuma, 37, wrote in the letter, "I repent of killing children (whom I didn't know)."

Ranking Osaka police officers flatly denied they had pressured Takuma.
