Senior Investigating Officer, Detective Superintendent Jim Dunkerley, said: “I would continue to appeal for anyone who has any information to come forward.
“This shooting happened in broad daylight in a busy part of Leeds so we firmly believe that there are people who witnessed this incident and who know who is responsible, but have yet to contact police.
“We are continuing to make enquiries and have made further arrests – but we still need to hear from those who have information.
“If you would prefer not to contact the police directly, I would urge you to contact independent charity Crimestoppers anonymously with any information.”
Anyone who has any information or witnessed anything suspicious in the area is urged to contact the police via 101.
Crimestoppers can also be contacted anonymously on 0800 555 111.
