A one-year-old boy has died and a girl of the same age is fighting for her life after they were found with critical injuries at a Finsbury Park flat.

Murder detectives have launched an investigation and have been searching the area for a suspect, with help from the police helicopter.

Officers and medics were called to a flat in Wilberforce Road at 11.10pm last night, and rushed the critically-injured children to hospital.

The boy died in the early hours and the girl is still in a critical condition.

Witnesses heard a woman shouting for help on the street outside and later saw two children being carried out of the property.

Mihai Menea, 29, who lives on the second floor of the building, said the children were twins and lived on the top floor with their Romanian mother and Indian father.

The father worked at the nearby Pembury Hotel as a receptionist, where Mr Menea also works, until a few days ago, he said.

A woman living opposite the building, who gave her name as Gui Gui, said she heard a woman shouting late last night and opened the window to offer help.

“I was watching TV,” she said. “I heard someone was shouting.

“She kept on shouting. I do not know what she was shouting.

“I opened the window and I asked her ‘Can I help you, can I call the police for you?’

“She said: ‘my kids’.”

She later saw two young children being carried out of the building, with one being held very close to a member of the emergency services.

Mr Menea described the mood inside the property as “tense”.

A police car remains parked outside the white three-storey building and neighbours said officers had been searching properties along the tree-lined street.

Next of kin have been told about the incident and no arrests have been made.

Anyone with information that may assist the investigation is asked to call police on 020 8345 3775.
