A, who was wearing an electronic anklet and living under house arrest on suspicion of sexual assault against a minor, harassed a probation officer by monitoring the screen of his mobile phone. A also threatened to spray hydrochloric acid at the probation office and filed malicious complaints. The Uijeongbu District Court indicted A for obstructing public duties and sentenced him to six months in prison. The court ruled that A had no remorse, as he claimed verbal abuse and abuse of power against the probation officer's legitimate guidance and supervision, and even mocked the victims in his petition for non-punishment.
