Birmingham police say: " Can you help us identify this man who has been seriously injured when he came off his bicycle in Harborne yesterday morning? The man in his 70s, who we believe had a medical episode, suffered a head injury when he collapsed in Station Road at about 10.25am. He's currently in a critical but stable condition in hospital. Officers are working to identify him and his next of kin, as we're concerned he may be a carer for someone. If you recognise him or the bike he was riding call us on 101 or message live chat quoting log 1135 of 5 May."
