The blaze broke out at a two-storey mid-terrace house on Riverside Place in Barry on the afternoon of June 24, prompting a major emergency service response.
South Wales Police confirmed that cannabis cultivation was found “spanning multiple rooms” of the property, including the attic.
A police spokesperson said on Thursday (June 25): “We remain at the scene of a house fire in Riverside Place, Barry.
“Evidence of a large-scale cannabis cultivation spanning multiple rooms including the attic has been found in the property.
“There was no-one in the house at the time of the fire, neighbouring properties were evacuated, and there are no reported injuries.”
Parts of Cardiff Road and Palmerston Road were closed on Wednesday afternoon (June 24) while emergency services dealt with incident.
A joint investigation is now underway with the fire service.
A spokesperson for South Wales Fire and Rescue Service said: “SWFRS received a call at approximately 3.09pm to reports of a domestic fire at Riverside Place, Barry.
“Crews, appliances, water bowsers, and an aerial hydraulic platform from Barry, Penarth, Ely, Cardiff Central, Maindee and Pontypridd attended the incident involving a fire on the first floor and roof space of a two-storey mid-terrace domestic property.
“The fire was extinguished using 45m jets, safety jets and breathing apparatus.
“The stop message was received around 5.54pm.
“The incident has been handed over to the police.”
It appears that National Grid have attended the property to make sure it is safe.
When cannabis cultivations are found, they often involve illegal interference with the electricity supply – including meter tampering.
Neighbours believe that the house has long been empty, and there appear to have been no reports of anyone living at the address.
Residents also believe that the homes on either side of the property were fully evacuated during the emergency response.
Visible damage to the property includes severe destruction to the roof and missing windows.
