Investigations are continuing a week on from a dramatic school bus fire near Port of Menteith which forced pupils to be evacuated.
The double decker service was ferrying kids travelling back from McLaren High in Callnader to Aberfoyle when it caught fire on a stretch of the A81 near the village last Wednesday.
Emergency crews rushed to the scene as the students were quickly rushed out of the bus as smoke continued to billow from the rear of the vehicle.
