A seven-year-old girl who was critically injured at a house in southwest London on Friday has died in hospital, police have said.
A man appeared at Wimbledon magistrates on Saturday morning, in connection with the incident, charged with attempted murder.
The court was told that the youngster was unlikely to survive.
The Metropolitan Police confirmed later the girl died on Saturday morning.
Robert Peters, 55, was remanded in custody until his next appearance, at Kingston Crown Court, on 1 December.
In court, magistrates made an order banning the reporting of any detail likely to lead to the identification of the victim.
A post-mortem examination into the girl's death is due to take place later.
