The body of the girls' aunt Kanticha Noon, 36, was also found in the home.

Norfolk Police today revealed the girls had died from knife wounds to the neck.

They said this had sparked a murder probe.

The force previously confirmed they are not looking for anyone else in connection with the deaths.

Cops revealed on Sunday that Bartlomiej and Kanticha had died of stab wounds to the neck, but were still awaiting the sisters' post mortem examinations.

Today's tragic findings came just hours after mystery deepend around the deaths, with more details emerging around Bartlomiej undergoing a mental health assessment.

The force referred itself to the watchdog, the Independent Office for Police Conduct, for attending the home on December 14 in connection with a missing person enquiry.

The dad was later discovered close to his home and was taken to the Norfolk and Norwich University Hospital to undergo a mental health assessment.

But it has now been revealed the dad left before any tests could be taken, with the hospital now releasing further details of his visit.

NNUH carried out a comprehensive review but the hospital does not provide mental health services, Eastern Daily Press reports.

A spokesman said: "We can confirm that the patient was taken to the emergency department by police on December 14.

"Following a comprehensive clinical assessment, the patient was assessed as having mental capacity and he left the unit before being reviewed again by the team.”

Police have also referred themselves to the police watchdog, after not responding to a call to the home earlier that morning.

The force said it had received a 999 call from the home not long before the bodies were found.

Sources confirmed that Bartlomiej was the man who made the call at 6am, which police failed to send officers out on.

However, officers were not deployed until a second call from a member of the public shortly before 7am.

Meanwhile, Detective Chief Inspector Chris Burgess, who is leading the investigation, today spoke to the girls' heartbreaking deaths.

He said: “We understand how incredibly shocking this incident is for all involved and for the wider community and that this latest update adds to the sense of heartbreak.

"Our thoughts are with the family of those found at the property grieving such a traumatic loss.

“We would like to thank the community for their help and will continue to provide reassurance patrols in the area.

"A cordon will remain on at the address whilst we finalise our detailed examination of the scene.”
