A 22-year-old woman was taken to hospital after being rescued from the water at a Norfolk marina.
Emergency services were called to the Fisherman's Bar at Burgh Castle Marina early on Sunday morning after reports of a woman falling in to the water.
She had already been pulled ashore by the time the emergency services arrived. People at the scene said she was in the water for about 10 minutes.
She was taken by ambulance to the James Paget Hospital for treatment.
The accident happened as an office party at the bar began to break up.
The woman's partner organised a boat and rope to help in the rescue when she fell into the water.
