This is quite an upsetting accident. I know the cyclist, not particularly well, but I have met him at a few events. He was very seriously injured, as far as I’m aware he is still in the spinal injuries clinic in Glasgow. I believe he is currently a quadriplegic with a slim hope of some improvement.
I don’t know details of the accident. As it is a signal controlled junction there has been an assumption by many that one party passed through a red light.
