A referral has been made to the police watchdog today over the deaths of a family in Norfolk - after police failed to attend a 999 call made from the address where their bodies were later found.
The bodies of Bartlomiej Kuczynski, 45, and his children were found inside the house in Costessey, near Norwich, alongside that of a 36-year-old woman, who has not been identified.
Norfolk Police confirmed they had received a call from a man at the address at 6am but officers did not attend.
Police were only sent to the house after receiving a second call at 7am from a member of the public, who was concerned about the people inside.
The four bodies were found after police broke in at 7.15am.
As a result, Norfolk Police confirmed that it had referred itself to the Independent Office of Police Conduct (IOPC).

The force said a separate IOPC referral had already been made over their involvement with the family on December 14, when Mr Kuczynski was reported to have gone missing and was later found walking nearby.
A Norfolk Police spokesman said: 'A second referral has been made to the IOPC today following the identification of a 999 call made yesterday morning at 6am by a man at the address and police resources were not deployed.
'Officers had been called to the address shortly before 7am after a member of the public called police to raise concerns for the welfare of people inside.
'Police arrived on scene at around 7.15am and forced entry to the address, finding the bodies of two young girls, a 45-year-old man and a 36-year-old woman.
'A police cordon remains in place and forensic investigations will continue today inside the property. Detectives have been carrying out house to house enquiries, speaking with witnesses and are continuing to exam local CCTV footage.
All four people were found with injuries and post-mortem examinations will be held in due course to establish cause of death.
Detective Chief Inspector Chris Burgess said: 'We're aware of commentary on social media and in news media, however, I would emphasise that formal identification is yet to take place.
'As I said yesterday, we believe the man and two children lived at the address, and while the woman was staying there, she wasn't a permanent resident.'
Police have requested anyone who may have been in the Allan Bedford Crescent area earlier that morning to come forward with information.
Police at the scene in Costessey, Norfolk, yesterday after four bodies were found at a property
The two little girls believed to have been killed were today described by neighbours as 'beautiful girls'.
The girls were identified locally as Jasmin Kuczynska, 12, and her seven-year-old sister who attended local schools and were often seen walking around.
Well-wishers including some crying girls left flowers in their memory today beside the police cordon outside their home in Allan Bedford Crescent, Costessey, near Norwich, Norfolk.
The sisters were found dead at the semi-detached house on Friday, alongside the bodies of their father Bartlomiej Kuczynski, 45, and a 36-year-old woman.
Detectives have confirmed that the four who died in the 'isolated incident' were two girls, a man and a woman who all had injuries.
Officers said they were from the same family and that the two girls and the man lived in the semi-detached house while the woman who died was 'visiting and didn't live at the property'.
Mr Kuczynski's Thai-born wife Nanthaka Kuczynska who was known as Nan had reportedly not been seen by neighbours for months.
Others said that her sister had recently moved in to help care for the girls and Polish-born structural engineer Mr Kuczynski who had been suffering from mental health issues.
Mother-of-two Jocelyn Atienza, 50, who lives nearby said: 'It is just awful. The two girls were lovely sisters and beautiful girls.

'They were nice girls who were a little shy. We used to see them walking around together. They would look really happy when they were out with friends.
'The older one would catch the bus to school, and her little sister would walk to the primary school by herself.
'Their mother was friendly and we always used to say hi hello to each other in the street, but I have not seen her around for some time.
'She always used to put up decorations for Halloween and Christmas outside their home, but her husband was putting up decorations instead of her last December.
'
Jasmin was a pupil at Taverham High School while her sister was a pupil at the Queen's Hill Primary School on the Queen's Hill estate where they lived.
Mr Kuczynski is understood to have lived in Britain for the last 20 years after graduating from Wroclaw University of Technology in Poland.
His home remained cordoned off by police today as white-suited forensic officers were seen going in and out of a large white tent erected beside the front door.
The Bishop of Norwich the Right Rev Graham Usher said wanted to offer 'Prayers for all impacted by this tragic news, especially the wider family and people from Costessey:.
He added: 'I've spoke to our local clergy who are offering support in the communities they serve and will be opening churches for those who want to come and pray or talk.'
