The Independent Police Complaints Commission have said that they have assessed the incident surrounding the death of Tom Maynard and have now referred it back to Scotland Yard.
They claim the pursuing officers had lost sight of Maynard and had no further contact with him before his death. 50 minutes then passed between the start of the police chase and Maynard being hit by the train.
The police evidence is that at 4.13am officers saw a car being driven erratically which they followed.
The driver then decamped and after a short chase on foot, officers lost sight of him and had no further contact. The man appears to have been hit by a train at 5.04am.
