Former Met Police commissioner Lord John Stevens faces an investigation over his disclosure to the Macpherson Inquiry in 1998.
The Independent Police Complaints Commission (IPCC) confirmed that the issue had been referred to them by the Met Police.
The Macpherson Inquiry found evidence of ‘institutional racism.’
Stephen was an 18-year-old aspiring architect stabbed to death by a group of up to six white youths in an unprovoked racist attack as he waited at a bus stop in Eltham, south-east London, with a friend on 22nd 1993.
A second review last year by Mark Ellison QC found that corruption allegations about a Metropolitan Police detective who worked on the original investigation into his killing should have been revealed to the public inquiry led by Sir William Macpherson.
Channel 4 News revealed last night that Stephen’s father Neville had made a formal complaint and sought an investigation.
The Met Police said: ‘The complaint has been made in relation to Lord Stevens‘s role as the then deputy commissioner and disclosure to the Macpherson Inquiry.’
Lord Stevens strenuously denies any allegations of wrongdoing.
When contacted by Channel Four News he quoted from a letter he had received from Mark Ellison QC: ‘No one is suggesting that you did anything that was culpable in any way.’
