Police have charged a musician who plays the drums in Prime Minister Stephen Harper's band with five counts of sexual assault and five of sexual interference with a minor.
Phillip Nolan, who is also a teacher with the Ottawa public school board, was charged in connection with incidents dating back to 1998 and 2000.
Police say they started an investigation last November looking at a complaint of sexual assault on a minor by a teacher.
They say there are concerns there may be other victims.
A spokesman for Harper said the Prime Minister's Office is ``shocked and disturbed'' by the charges and had not been made aware of any such allegations.
Nolan was the drummer for Harper's band, Herringbone.
