Two nine-month-old twins have reportedly been mauled by a fox while they slept in their beds.
The baby girls are now seriously ill in hospital after the attack in Homerton, east London, on Saturday night.
Police have said that the fox apparently got into the house through an open door on the ground floor and then went upstairs and attacked the twins.
The babies are reported to be in a "serious but stable condition" at the Royal London Hospital.
They both have injuries to their arms and one of the girls is thought to have facial injuries.
Their four-year-old brother was also asleep upstairs but was not injured.
A Scotland Yard spokesman told AOL News: "Police were called at approximately 10pm on Saturday June 5 to an address in Homerton E9 to reports of a fox attack.
"Officers and the London Ambulance Service attended and found two nine-month-old girls with injuries.
"Both babies were taken to an east London hospital where their condition is described as serious but stable."
This isn't the first time a baby has been injured by a fox. Back in 2002 Sue Eastwood, from Kent, said her 14-month-old baby boy Louis was injured after a fox got into their house.
He was left with bite marks on his head after the fox got into the sitting room of the house while the mother slept.
In 2003 a four-year-old girl, Jessica Brown, was attacked in her garden in Tufnell Park, north London and bitten on the arm.
The Daily Telegraph reports that there are around 27 foxes per square mile in urban areas of England.
However the RSPCA says attacks on humans by foxes in the UK are extremely rare.
