Sergeant Steven Jones said: “This swift and thorough investigation involved officers and staff from departments across the division, who worked together to secure this result.

“The defendant had a huge amount of heroin at her home, with efforts taken to conceal bags of the drug around the property.

“There is no doubt that in taking Proffitt out of the supply chain we will have disrupted an organised crime gang which she was a trusted part of in supplying heroin into the division.”

Officers carried out a warrant at the 52-year-old’s home in South Road on August 30, 2020.

On searching the property, a box containing 408g of heroin was found concealed in a vent under the staircase, and two further wraps were found in a shower head bracket. Fingerprint marks matching those of Proffitt were found on these items.

Four mobile phones were also seized from the property.

Sgt Jones said: “The quantity of heroin recovered is far in excess of what he would expect to see someone who is simply a user to be in possession of for their own use.

“Given the value of the heroin recovered and the financial circumstances of the defendant, we were confident it was unlikely she would be able to fund a purchase of such a quantity of heroin without being involved in the supply of drugs.

“The only realistic reason for possessing this quantity of heroin was for supply onto others.”

Proffitt was charged with possession with intent to supply, and pleaded guilty. She was sentenced to 57 months in prison when she appeared at Swansea Crown Court on Thursday, November 26.

Meanwhile, the drive-through facility at Canolfan Rheidol has now been relocated to Cardigan in response to a rise in cases in that area. Residents of Aberystwyth will not be impacted by this move as there is plenty of testing capacity at the LTS.

Alison Shakeshaft, Director of Therapies & Health Science at Hywel Dda University Health Board, said: “We are very pleased to have secured this LTS for the people of Aberystwyth. Many residents in the town, including students, do not have their own private vehicle in order to access drive-through testing facilities, so the option of a walk-in facility is very important.

“This is a challenging time and I urge everyone to remain vigilant and follow the rules, including wearing face coverings where required, maintain social distancing, washing hands regularly, or using a hand sanitiser if hand washing is not possible.”
