A corrupt Lancashire police officer helped his gangster brother by hiding weapons and intimidating witnesses, it has emerged.
Salim Razaq pleaded guilty last month to perverting the course of justice, possessing firearms and ammunition and misconduct in a public office.
Reporting restrictions were lifted at when he was cleared of mortgage fraud at Liverpool Crown Court.
Razaq was sacked by Lancashire Police in June.
Razaq, 33, of Chorley Road, Walton-le-Dale, was caught when he plotted to help his brother Hafiz, known as "The Enforcer" and "Big Haf", escape prosecution for his role in a turf war between drugs gangs in Preston.
His brother Hafiz, 25, of HMP Manchester, mother Gulshan Razaq, 58, of Chester Road, Preston, and three others have also admitted charges in relation to the case.
Police bugged phone calls that Hafiz made from prison to his brother while awaiting trial for kidnapping.
The pair were overheard discussing money laundering and witness intimidation plans.
Lancashire Police's Professional Standards Department raided the sergeant's home in March and found a Sten machine gun and two Uzi machine guns hidden under the stairs.
They also seized 228 bullets, a bullet-proof jacket and a balaclava and a knuckle duster.
A total of £72,000 was found in Razaq's bedroom.
Razaq joined Lancashire Constabulary in March 2001 as an emergency response officer and worked his way up to the rank of sergeant, covering Nelson, in January 2009.
Razaq and the five others are due to be sentenced on 11 November.
Gulshan Razaq admitted perverting the course of justice. Hafiz Razaq admitted two counts of perverting the course of justice and money laundering.
Jason Lawrenson, 26, of HMP Preston, and Daniel Cookson, 25, of Yewtree Avenue, Ribbleton, admitted money laundering.
Louis Bamber, 22, of HMP Liverpool, admitted possession of a firearm.
Salim Razaq was also accused of inflating his £33,000-a-year police salary to get a mortgage.
But Judge Henry Globe QC, at Liverpool Crown Court, who lifted the reporting restrictions, ruled that Razaq did not break the law and ordered the jury to return a verdict of not guilty.
Andy Cooke, Assistant Chief Constable of Lancashire Police, said: "Salim Razaq was nothing short of a criminal in a police uniform and I am appalled by the fact that a police officer was involved at the level he was in this criminality.
"However, I am extremely proud of the Lancashire officers who put this case together, the quality of which is reflected in the guilty pleas.
"We are resolute in our commitment to root out any bad apples that fail to maintain the high standards of professional behaviour and integrity which the vast majority of our staff adhere to."
