Bolton park assault 'was an accident'
Police investigating how a 12-year-old girl got a serious head injury in a Bolton park have concluded it happened by accident.
At first the girl said she had fallen off a swing at Bobby Heywood's Park on Wednesday evening.
Then on Friday her family reported to police that she had been assaulted by four older girls.
An independent witness, who was in the park, said the girl fell off her bike and banged her head, police said.
There was "categorically no other person involved", they added.
The girl has now been released from hospital and is making a good recovery.
