A kilo of cocaine was found at Haberdashers’ Aske’s Boys’ School as part of an organised drug network.

Three men were arrested in October after a drugs warrant was served at the school in Elstree, following an investigation into a Hertfordshire drug network.

During the search, a kilo of cocaine was discovered at the school, and two kilos were seized at a hotel in the Wirral area where one of the men was staying, around £100,000 in cash was also recovered.

Justin Terry, 45, who is a former caretaker at the school, was among the three men who appeared at St Alban’s Crow Court on Wednesday (October 7).

Terry pleaded guilty and was sentenced to 8 years for conspiracy to supply class A drugs.

The other two men, who also pleaded guilty, were:

• Martin Walsh, 54, from Churchfields Road, Watford – sentenced to 8 years for conspiracy to supply class A.

• Philip Blackburn, 38, from Mimas Road, Hemel Hempstead - sentenced to 10 years and 2 months for conspiracy to supply class A.

Detective Chief Inspector Doug Black, from Hertfordshire Constabulary’s Serious and Organised Crime Group said: “Following a long running investigation, we covertly watched and gathered evidence on this crime group who were supplying drugs in the county and beyond.

“The sentences handed out will have a major impact on the supply of drugs within Hertfordshire and will also make the county and safer place for those living here. Those involved have been sentenced to date to more than 30 years in prison, and will no longer pose a threat to the community, a further six defendants are awaiting sentence.

“We will be acting to seize any assets that have been accumulated with illegal funds under the Proceeds of Crime Act to ensure that they do not profit further from their crimes.”

He continued: “Operation Relentless is Hertfordshire Constabulary’s response to the on-going threat from organised criminal gangs. These groups pose a threat to local communities and the force is committed to identifying and relentlessly pursuing individuals and networks involved in serious and organised crime.

“ As part of this work, we depend on information from members of the community to help us crack down on drug-related crime. Any information you can provide, no matter how small it may seem, could help us to identify and apprehend drug dealers.”
