An Oahu grand jury indicted former Sacred Hearts Academy teacher William Plourde Tuesday with six counts of third-degree sexual assault and one count of first-degree sexual assault, according to the Department of the Prosecuting Attorney.
Plourde turned himself in to authorities last Wednesday. He is in custody on $200,000 bail.
According to court documents, Plourde met the alleged 15-year-old victim, on the morning of June 9 in Mililani Mauka. Police say the sexual assault took place in Plourde's car.
Plourde was a teacher at the all-girls school since 1984.
