A teenage girl was killed and her body discovered in the back of a car following a road accident which may have been staged to cover evidence of the crime.

Police launched a murder inquiry after the body of 16-year-old Megan Bannister was found in the back of the car at the scene of the accident in Leicestershire, on Sunday.

A post-mortem established that Megan had been killed before the accident, which police believe may have been deliberately staged.

A friend of the teenager revealed that Megan had told her parents she was going to a friend for a sleepover, but instead arranged to meet an older man.
