Now a month after the incident police have released this picture and appealed to Khan to come forward.
Police wish to speak to Mr Khan to establish what happened on the night of the incident.
Detective Sergeant Paul Hughes from the Serious Collision Investigation Unit said: 'I want to appeal directly to Kashif Khan to come forward so that we can establish what happened that night.
'I would also appeal to anyone who has information regarding his whereabouts to get in touch.
'The response from the public following the release of CCTV images was excellent and I would like to thank everyone that got in touch and continue to appeal to anyone with information to contact us.
'I want to also ask people to not speculate on social media. This does nothing to assist us or the family of Andell during this really difficult time.'

Emergency services attended but the cyclist was pronounced dead at the scene.
Police believe there were four men in the car at the time of the collision and that all four fled the scene.
They are currently trying to identify and trace those in the car at the time.
