Tributes have been paid to a motorcyclist who died after a crash with a bin lorry.

Daniel Piaszczynski, 20, was killed after a collision on Dunkeld Road, Perth just after 8.30am on Wednesday.

The former St John's Academy pupil was a sales assistant at Currys PC World in the city's St Catherine's Retail Park.

Stuart Doherty, regional manager of parent company Dixons Carphone, said: "'The whole team are in shock.

"I was speaking to Daniel the day before and as always he was bubbly and energetic and making a huge difference to our customers.

"He was a much valued member of our team and he was friends with everyone.

"He had a very bright future with us.

"Our thoughts are with Daniel's family and friends at this very difficult time.''

Friends posted warm tributes on Daniel's Facebook page.

A colleague wrote: "Utterly shocked to hear of the loss of Daniel Piaszczynski.

"A gentle giant of a man and somebody I'll always remember for being a thoroughly good bloke and a joy to be around.

"My thoughts are with his family, in particular his brother Adam, also a great man with the same good values and politeness as Daniel.

"He'll live on in people like us who he had a such a positive effect on."

And a former classmate posted: "R.I.P Daniel, you were a great guy, and always made school a little more bearable for me (especially Chemistry!). Always caused smiles on the folk you were around, each and every day. You'll be missed dearly, buddy!"

Police want to speak to the occupant of a light-coloured Land Rover Discovery which was travelling north on Dunkeld Road, near to St Catherine's Road, around 8.25am on Wednesday.

Officers believe the person may have seen what happened before the crash.

Any witnesses are asked to contact police on 101 and quote incident 0637 of December 20 2017.
