A 16-year-old girl in Sasebo, Nagasaki Prefecture, suspected of killing and dismembering her classmate Saturday, had no personal trouble with the victim, police said Tuesday, retracting earlier information that a personal grudge may have been involved.

The suspect, whose name is being withheld because she is a minor, told police she had no grudge against the slain classmate, and investigators have so far not been able to confirm any personal trouble between the two, according to Nagasaki police.

A senior official at Sasebo Police Station, who initially released information indicating otherwise, corrected his remarks later Tuesday.
