`Police station' trap.
The flat, in a converted police station, was also watched.
One of the customers seen going into the house was Alan Titford, 27, of Treowen, Newtown.
He admitted three charges of possessing heroin, a class A drug, and was yesterday jailed for six months at Mold Crown Court. The court heard that the listening device was hidden at the Old Police Station, in New Street, Welshpool between June 15 and 21.
Robert John Jones, who lived at the flat, and others have admitted being involved in dealing and were awaiting sentence.
David Potter, defending, said his client was no longer taking heroin.
