Claims of “discreditable conduct” by Metropolitan Police officers after the murder of teenager Stephen Lawrence are to be probed by the police watchdog.
The Independent Police Complaints Commission will examine the behaviour of the head of the Met’s counter-terrorism unit Cdr Richard Walton.
It is alleged he got information from a police spy about the Lawrence family, “potentially undermining” the inquiry.
The IPCC will also look at the conduct of two former officers.
Imran Khan, a solicitor for Stephen’s mother, Baroness Lawrence, said: “We believe that this is a strong test for the IPCC because they recently had to apologise to Mrs Lawrence for the failure of their investigation into corruption in 2006.
“What Mrs Lawrence now wants is a proper independent – with a capital “I” – investigation into this matter and results which show the IPCC has got teeth.
“I want to say to those in charge of the IPCC that Mrs Lawrence is looking at you with great scrutiny and you ought to do a better job than you did in 2006.”
The watchdog said it would look at claims Mr Walton “met with an undercover officer and obtained information pertaining to the Lawrence family and their supporters, potentially undermining the inquiry and public confidence”.
