POLICE set up a hidden camera in a surveillance operation to catch drug dealers operating from a house in Redditch, a court heard.

They saw people going to the front door of the semi-detached house at 15 Abbey Road, and after watching for three weeks, they carried out a raid.

They found 37-year-old Carol Munro in the lounge and her partner David Gibbs upstairs trying to flush a quantity of heroin down the toilet, Charles Hardy, prosecuting, told Worcester Crown Court.

Police found more heroin and some scales inside the house. They stopped two people leaving the address, who were both found to be in possession of drugs.

Mr Hardy said Gibbs and another man, Calvin Harvey, had pleaded guilty earlier this year to conspiracy to supply drugs from the premises from September 16 to October 9, 2009, when the surveillance took place. A third man alleged to be involved has died.

Munro, also known as Georgina Adkins Munro, denied the charge. She was found guilty of conspiracy after a two-day trial.

She was released on bail fo reports and will be sentenced with her accomplices on October 31.

"She was not the prime mover but she played a role in the dealing of heroin," Mr Hardy said. The surveillance footage showed Munro opening the door and letting people into the house. She denied any involvement and said she did not know it was going on.

The jury was shown part of the surveillance footage which showed visitors to the house on a regular basis, usually staying for just a short time.

Jason Aris, defending, said Munro did not know the people she let in through the front door. They were friends of her partner and she gave one his bus fare and another one cigarettes and a lighter.
