Police were called to Frobisher Close in Thetford just after 5.30pm on Monday after concerns were raised by an attending ambulance crew.

A woman in her 40s was pronounced dead at the scene.

Five people have been arrested in connection with the incident and were in police custody yesterday for questioning, but officers do not believe there is an ongoing threat to the wider community.

The property remained cordoned off yesterday while investigations continued and forensics teams examined the scene inside the semi-detached house.

Residents were shaken by the news, attesting that their cul-de-sac on the Admirals estate was normally a 'very quiet street'.

One resident, a close neighbour of the deceased woman, said: 'She kept herself to herself, but then most of the people around here do.

'It is a quiet little cul-de-sac. It is awful to hear about something like this happening.'

One couple said it was the most serious incident they had seen in the cul-de-sac in 30 years.

They added that it was a 'lovely street', with street parties being held there in the past.

Thetford town councillor Sylvia Armes, who has lived on the Admirals estate since the 1960s, said: 'It is terrible for this to have happened on the estate. It is a reasonably trouble-free area. I know we have our own little neighbourly problems, but this is just devastating news.

'I am so sorry for the family. It is absolutely shattering.

'People tend to blame other estates when there is trouble, but this shows you cannot do that because you never know what is going to happen in this day and age.'

T/Detective Chief Inspector Marie James said: 'Although we are in the early stages of this investigation we have a number of significant enquiries which, I hope, will help us to understand the events which lead to this woman's death.

'I would like to reassure the public that we currently believe those involved to be known to each other and that there is no ongoing threat to the wider community.'

Dave Hodgkinson, a former chair of the Norwich Road Residents' Association, said he heard the sirens pass his street on Monday night but was unaware of the unfolding events.

'It is normally a very quiet and uneventful estate, one of the quieter estates in Thetford. I cannot think of anything like this occurring while I have lived here.'

Anyone with information about this incident is asked to contact Norfolk Constabulary on 101 or Crimestoppers anonymously on 0800 555111.
