Norfolk Broads deaths were 'domestic incident' say police

Part of the River Bure was closed in the early hours of Sunday morning for the search

The deaths of a couple from Surrey, whose bodies were found in the Norfolk Broads, are being treated as a "domestic incident", the police said.

Their bodies were found on Sunday after the woman's 13-year-old daughter was found alone on a hire boat on Saturday.

Post-mortem examinations have shown the woman was probably strangled and the man drowned.

The police have said they are not looking for anyone else in connection with the deaths.

Det Supt Jess Fry said: "All circumstances point to this being a domestic incident and we will continue to investigate in order to put a full set of evidence before the coroner.

"[The coroner] will consider the full sequence of events and evidence gathered at inquest.

Taking overdose

"We will therefore not be releasing any further investigative updates or commenting on speculation."

The couple, who were in their 40s, were found between Salhouse Broad and Wroxham Broad, near to where the boat was found tied up.

The police said the man, who is a foreign national, is thought to have committed suicide and might have also used another method in addition to drowning, such as taking an overdose.

It is understood the girl, who was found unharmed, was cared for and fed throughout last week and it is not thought she was locked inside the boat.

She has been interviewed by officers and is now being comforted by family members.

The police said the names of the deceased will be made public once formal identification has taken place.
