Wimborne drug suppliers jailed

Grant Putman and Brooke Marshall were arrested in Old Manor Close in Wimborne Minster back in August 2025.

A man and woman from Dorset have been jailed for drugs offences and money laundering following an investigation by the South West Regional Organised Crime Unit (SWROCU).

SWROCU officers executed a warrant at the home of Grant Putman, 33, and Brooke Marshall, 35, in Old Manor Close in Wimborne back in August 2025.

Police found quantities of white powder scattered across the kitchen worktop, a bucket containing a kilo block of cocaine and bags of cannabis, hundreds of illegal vapes in boxes on the floor and on the shelves, and THC products and cannabis resin in the fridge.

Paraphernalia associated with the preparation of drugs and equipment used for the packaging and posting of products were also prominent. In the open safe in the pantry, more drugs were found in a plastic confectionary tub, along with thousands of pounds of bundled cash.

In total, officers seized one-and-a-half kilos of cocaine, 400 grams of heroin, 500 grams of ketamine, two kilos of cannabis, approximately £20,000 in cash and a knuckleduster.

Both Putman and Marshall pleaded guilty to being concerned in the supply of cocaine, ketamine and cannabis. Putman also pleaded guilty to possession with intent to supply heroin and possession of an offensive weapon in a private place, while Marshall pleaded guilty to money laundering.

On Thursday 16 April at Bournemouth Crown Court, Putman was handed six years and six months in prison and Marshall was given three years and eight months.

DS Stuart Cumine of SWROCU said: “With the support of our colleagues in Dorset Police, we were able to act upon intelligence that drugs were being supplied from this residential address in the market town of Wimborne.

“The pair were making significant sums of money operating from their family home distributing drugs and THC products in the community and to customers across the UK through the postal service.

“The strength of the evidence was such that both Putman and Marshall pleaded guilty to the offences, and the supply of these harmful drugs, which cause undeniable harm to communities, has been disrupted.”
