POLICE investigating the attempted murder of a former British agent who infiltrated the IRA have denied accusations that the peace process is hampering their probe.

Martin McGartland who was shot six times at his "safe house" home in Whitley Bay and Unionist MP Martin Maginnis say they suspect political interference.

But a Northumbria Police spokesman, who rejected the charge, said last night: "Two years on from the shooting of Martin McGartland, Northumbria Police are continuing their inquiries to find his attackers.

"Officers believe the answer lies in DNA material found after the shooting in 1999. Two people were questioned in connection with the attack, but released."
