A FURIOUS father says his disabled daughter, 11, was tied up on a school bus, and is considering legal action.
Michael says Caitlyn was restrained by staff trying to stop unruly behaviour, including scratching at seats.
He said his daughter had told him force was used to bind her wrists with rope.
The principal of the Ballarat Specialist School said he believed shoelaces were used by bus staff to secure Caitlyn to her seat.
Police and the Education Department are investigating an August 29 incident.
A police spokesman said a Ballarat man was interviewed yesterday.
