Former police chief Norman Bettison will be investigated by a watchdog over claims he tried to influence a witness who gave evidence in the Macpherson inquiry.
The Independent Police Complaints Commission (IPCC) will independently investigate the referrals from West Yorkshire Police and the West Yorkshire Police and Crime Commissioner.
Norman Bettison was the Assistant Chief Constable at the time in 1998 of the Bradford inquiry.
IPCC deputy chair Deborah Glass said: “In the absence of legitimate justification, there is an indication of misuse of police information systems and unlawful processing of the witness’s (sensitive) personal data which would be a clear indication of recordable conduct concerning this tasking.
“The investigation, which will be overseen by IPCC Commissioner Cindy Butts, should also consider whether the tasking was motivated or influenced by racial discrimination.”
