Detectives have renewed an appeal for information about the fatal shooting of a 22-year-old man last summer.
Marvyn Bradshaw from Nottingham was shot dead outside the Sporting Chance pub in Basford in August.
One man is on remand awaiting trial for his murder and on Tuesday two others were remanded in custody, charged in connection with Mr Bradshaw's death.
However, police want more information about a fourth man, and are offering a £10,000 reward.
Marvyn Bradshaw was shot as he drove his friend's car out of the car park and died of his injuries in hospital.
