An 11-year-old schoolgirl who told Internet chat-room visitors that she was planning to kill herself was traced by Attica electronic crime squad officers who informed her parents, it was revealed yesterday. Working on tipoffs, police traced the messages to the girl's home and informed her parents that the girl had expressed her intention to commit suicide, citing personal problems. The parents said they had not been aware that their daughter was unhappy. The girl has been placed under the supervision of a psychiatrist and is already feeling better, according to police. It is the seventh such case to be tackled by electronic crime squad officers in the past two-and-a-half years. In February, an 18-year-old boy who had told chat-room acquaintances he was planning to kill himself was traced by police.
