Friends of the man missing since his boat capsized on a remote stretch of the Broads have joined in the search for him.

Nathan Strowger, 30, was with four other people when their small craft sank on the River Waveney, between Beccles and Oulton Broad, on Monday night.

The other four were able to get to safety, but despite a major search operation by the emergency services Mr Strowger remains missing.

As the efforts continued today, his friend Adam Winyard, from Carlton Colville, joined the operation on the river, near to Aldeby and Barnby.

"After reading what happened, I straight away came here on my boat to help with the search," he said.

"I am worried sick. I have been friends with Nathan for years, we grew up together.

"Having been away for the last couple of days I haven't had a phone signal, so it came as a horrible shock, we are all worried sick for him."

Mr Winyard, 28, a childhood friend, said Mr Strowger lived on a boat on the Waveney and was familiar with the waterways.

The vessel which capsized was his small dinghy, which was fitted with an outboard motor.

The latest searches of the river have been coordinated by Norfolk police's Marine Team.

The emergency services remained at the scene throughout Tuesday and Wednesday, with boats combing the river and divers conducting underwater searches.

The spot where the boat sank is among those most inaccessible on the Broads, with road access via long tracks across the marshes.

Mr Strowger's relatives have been informed.
