THE parents of a five-year-old boy and his four-year-old sister have been arrested after their children were found stabbed to death.

The young victims and their six-month-old baby sister were all discovered with stab wounds on Friday night by police at a £300,000 suburban house in Park Lane, Carshalton, Surrey.

Paramedics carrying a “limp bundle” dashed from the property to waiting ambulances and tried to resuscitate one of the children. Another was wheeled out on a stretcher.

Officers arrested their father aged 39 and 35-year-old mother at the scene.

Police were called to the detached brick-built house at 10.30pm and found the children with “serious stab wounds”. They were taken to hospital but the pair died within minutes of each other, just before midnight.

“They were taken to separate hospitals where the older boy and girl were both certified dead about an hour later. All of the children are related,” a Metropolitan Police spokesman said.

The youngest girl is in a stable condition in hospital.

Jon Bailey, 22, a neighbour, described how paramedics tried to save the children's lives in the street.

“I saw the child being carried out in a white sheet. The sheet was practically all red - completely soaked in blood,” he said.

“The paramedic dropped her on a bed at the back of the ambulance and was trying to resuscitate her.”

Jim Duffy, another neighbour said: “It took a long time for the next child to come out - maybe half an hour. The second child was on a stretcher with wheels and they rolled it straight into the ambulance.

“I asked an ambulance worker if they were going to be okay. She shook her head first and then said ’I don’t know’ - perhaps that was a clue.”
