A woman who was found dead with stab wounds next to the body of a father and his two young daughters is the children's aunt who was visiting from , a friend has said. 

Kanticha Noon, 36, had arrived in the UK on December 27 and was staying at the family home with her sister Nanthaka's engineer husband, Bartlomiej Jakub Kuczynski, and their daughters, seven-year-old Downreuang and Jasmin, 12.

Nanthaka had reportedly not been seen by neighbours for months. 

Police are investigating after the bodies of Ms Noon, Mr Kuczynski and the girls were found at the property in Costessey, near Norwich, on Friday.

'She was very nice and caring to all friends of her, a really big supportive person, she helped everyone,' Ms Wathanakul

. 

Ms Wathanakul said her friend had visited the UK last June and had been hesitant about coming over this month.

She said: 'She didn't want to go to the UK this time for no reason because she went there once or twice a year normally.'

Ms Wathanakul went on to say: 'She loved her nieces, I always saw their pictures together. She is a single woman, no boyfriend, no husband, that's why she spent most of her time with those lovely girls.' 

A man called 999 from the property on Allan Bedford Crescent at around 6am on Friday, but police were not dispatched there.

Officers made the discovery about an hour and 15 minutes later after a member of the public alerted them at around 7am.

Norfolk Police, which has referred itself to the police watchdog over the delay, is not looking for anyone else in connection with the tragedy.

A pile of floral tributes, and two unicorn toys, had been left a short distance from the house today.

The items were left by the sign for Stony Grove, a road which joins Allan Bedford Crescent, with the house remaining taped off by police and with a number of marked vehicles still at the scene.

The family were named locally by neighbours who told of their shock at the tragedy (pictured is one of the girls)

One of the tributes said: 'Jasmine, you were such a sweet, caring girl, yourself and your sister didn't deserve to have your lives taken away.

'You would always be smiling in primary school. Fly high beautiful girls.'

Another said: 'You will be missed. I'm sorry to whoever was in the family and is going through it. Sorry Jasmin.'

Matthew Cross, headteacher at Queen's Hill Primary School and Dr Roger Harris at Taverham High School said in a joint statement that extra support was in place for pupils and staff.

'Both our schools have worked closely alongside colleagues from Norfolk County Council's critical incident support team over the weekend to ensure we have extra support and provision in place so we can meet the needs of both our pupils and staff at this difficult time,' they said.

Post-mortem examinations carried out on Sunday found the 45-year-old man died of a stab wound to the neck, while the 36-year-old woman died of a number of stab wounds to the neck.

The bodies of the two girls will be examined on Wednesday.

Detectives said the man and two children lived at the address, but the woman was visiting and lived elsewhere.

All four were found with injuries.

The force had already referred itself to the Independent Office for Police Conduct on Friday over police contact about a missing person inquiry at the address last month.

Detective Chief Inspector Chris Burgess, who is leading the investigation, said: 'We remain satisfied no one else was involved in this incident.

'I would like to thank the community for their support and for the many people who have called offering information.

'We continue to work through this and will get back to everyone who has been in touch. 

'The police cordon remains in place at the scene and we will continue to have a presence in the area tomorrow.'
