The driver of a car involved in a crash in Otsu that left two pedestrians dead, a boy and girl, both 2, has told investigators she was not paying enough attention when she made a right turn and hit a minivehicle that was traveling in the opposite lane at an intersection, police sources said on Thursday.

The driver of the car, Fumiko Shintate, 52, was arrested at the scene of Wednesday's accident and police are investigating her on suspicion of negligent driving resulting in death and injury.

The driver of the minivehicle, Michiko Shimoyama, 62, was also arrested at the scene but released later Wednesday after the police apparently deemed she did not have a high degree of responsibility for the accident.
