A 53-year-old man has been charged with murder after a man rescued from the River Wey in Surrey died in hospital.
Dominic Kelly, 57, of no fixed abode, died on Wednesday night at the Royal Surrey County Hospital where he was taken after the incident on Tuesday.
He was pulled out of the river by the emergency services just after 1200 GMT at Dapdune Wharf in Guildford.
Kenneth Lloyd, of no fixed abode, was remanded in custody after appearing before Woking magistrates.
He is next due at the Old Bailey on 4 March.
Detectives are appealing for a jogger who stopped to try to help Mr Kelly to come forward.
The man was running along the towpath close to the Odeon cinema, near Bedford Road, at the time and police believe he may be able to help their investigation into what happened.
The jogger initially stopped at the scene and told other witnesses he was going to look for some rope, but he did not return.
He is described as black, aged in his 20s, of slim build, about 5ft 5in (1.6m) tall and was wearing a tracksuit.
