A sniffer dog at Manchester Airport helped Border Force officers find at least 50 kilos of heroin, worth about £5m, hidden inside a shipment of carpets.
The seizure was made In April when officers became suspicious of a 46-piece consignment of hand-made knotted carpets that had arrived from Peshawar in Pakistan via Abu Dhabi.
