Sir Norman Bettison was Assistant Chief Constable of West Yorkshire Police at the time of the 1998 inquiry into police conduct while investigating the death of Stephen Lawrence.
Police and Crime Commissioner Mark Burns-Williamson said he referred Sir Norman to the IPCC after being made aware of three documents following a "thorough" search requested by the current West Yorkshire Police Chief Constable Mark Gilmore. PCC Burns-Williamson said:
These documents raise significant concerns over the role of Sir Norman Bettison in commissioning a report to be prepared in the respect of a key witness appearing before the Macpherson Inquiry.
This may suggest an attempt to intervene in the course of a public inquiry and influence the manner in which the testimony of a witness, who was due to present evidence before it, was received.
