The inshore lifeboat was called to a report of a man in the River Adur, Shoreham, shouting for help and in distress with a head injury.
The crew pulled him from the water and got him into the lifeboat. They then found another man who was drunk in a drifting boat on the river. The man in the water was taken back to the quayside and taken to hospital by ambulance. The boat was towed to the Sussex Yacht Club and the man on board was handed over to police.
