No new evidence found say Lawrence inquiries

Reviews were carried out by both the Metropolitan Police Service and the police watchdog the Independent Complaints Commission (IPCC) after the claims.

It followed reports alleging to have uncovered new evidence that corruption may have hampered the original investigation into the racist murder of the teenager in 1993.

David Norris and Gary Dobson were convicted of Stephen’s murder in January this year – 19 years after the crime – and sentenced to life at the Old Bailey.

Stephen’s mother Doreen Lawrence called for a fresh public inquiry after it was claimed the Met Police withheld paperwork from the Macpherson Inquiry.

The force launched a review to examine the claims, while the IPCC reviewed its 2006 investigation into complaints following the broadcast that year of the BBC programme The Boys Who Killed Stephen Lawrence.

The watchdog said its review followed reports on allegations made by former Met police officer Neil Putnam about the relationship between former Detective Sergeant John Davidson and Clifford Norris, David Norris’s father.

But yesterday the IPCC said it found that no new information or evidence has been made available that would lead to a change in the conclusions.

In a separate review, the Met Police’s Directorate of Professional Standards (DPS) found no evidence of corruption or collusion which could have influenced investigations.
