Police Scotland want to speak to a 4×4 driver who may have witnessed a fatal accident in Perth.
Officers believe the occupant of a light coloured Land Rover Discovery – which was travelling northwards on Dunkeld Road, near to St Catherines Road, at about 8.25am on Wednesday – may have seen the events prior to the crash.
Emergency crews were called out to Dunkeld Road five minutes later following a two-vehicle collision between a motorcycle and a skip lorry.
The incident involved a white Kawasaki and a lorry owned by the Binn Group.
Friends and colleagues have paid tribute to him as a “gentle giant”.
Any witness is asked to contact 101 and quote incident 0637 of 20 December 2017.
