Girl, 5, who died after being stabbed in flat named as Sayagi Sivanantham

A girl who died after a knife attack in a south London flat has been named as five-year-old Sayagi Sivanantham.

Officers and paramedics arrived at the address in Mitcham at around 4pm on Tuesday following reports that two people had been injured. Sayagi and a woman, 35, were found at the scene by officers with life-threatening knife wounds.

A neighbour who rushed into the flat to help said she discovered the woman ‘lying in a pool of blood’ with the lifeless girl next to her.

The pair were rushed to hospital but the little girl was pronounced dead shortly afterwards. The woman remains in a critical condition in hospital.

The Met Police said it is believed that both were known to each other.

No arrests have been made and police said they are not looking for anyone else in connection with the incident.

The incident is being treated as unexplained but it is believed to be non-suspicious.

Formal identification has not yet taken place, but the Met said it is confident the victim is Sayagi.

Neighbour Elsa Gonzales, 47, described the little girl as ‘cheeky’ and ‘always smiling’ after she recalled the trauma of finding the severely injured pair in the bedroom yesterday.

‘I saw the woman lying on the floor in a pool of blood,’ said Mrs Gonzales, who used to work in an emergency department.

‘There was blood everywhere. I looked on the bed and saw the girl, she was covered in a blanket.’

Mrs Gonzales, who has lived at Monarch Parade for 12 years, said: ‘It’s really breaking my heart, the child was a smart kid, she was always smiling.

‘She was a cheeky little girl, always playing with the neighbourhood kids.

‘To see her so lifeless, it’s like my heart is bleeding.’

Detective Chief Inspector Justin Howick said: ‘This is a tragic incident and we are working very hard to fully understand what has happened.

‘Whilst I know the effects of this incident will, understandably, shock and sadden the local community, please be reassured that we are not seeking anyone else in connection with Sayagi’s death and there is no cause for the community to be fearful or alarmed.

‘I would like to hear from anyone who feels they may have information that could assist our investigation.’

Labour MP for Mitcham and Morden, Siobhain McDonagh, tweeted: ‘Truly tragic events in Mitcham over the last 2 days. My sincere condolences to family & friends.

‘My thoughts are also with neighbours & residents who have witnessed such tragedy.’

Superintendent Richard Smith added: ‘Today a family are grieving for their little girl, and we are doing everything we can to support them.

‘This terrible incident has left a family distraught and the local community in shock. I would like to pay tribute to the police officers and ambulance service colleagues who responded to this frightening situation and thank them for working so hard to try and save Sayagi.

‘She will remain in our thoughts.’
