A driver who killed a pensioner is under investigation after appearing in mobile phone footage posted online from inside a Birmingham prison.
Kamran Raja from Acocks Green, was driving at almost double the speed limit on a Black Country dual carriageway in April last year when he crashed into Edward Harris' vehicle.
