Authorities have seized 33 fuel stations in Telangana and Andhra Pradesh with the busting of an inter-state gang cheating the consumers by using electronic chips to manipulate discharge of fuel.The police and the legal metrology department of both the Telugu states conducted joint raids and apprehend the gang, which was installing integrated chips in filling machines at fuel stations to dispense less fuel than the actual display on the filling machine board.The police said for every 1,000 ml of petrol or diesel, these fuel stations were dispensing 970 ml.Cyberabad Police Commissioner V.C. Sajjanar announced the arrest of the gang on Saturday. He said that integrated chips (ICs) programmed with manipulated software were installed with the connivance of fuel station owners, causing loss of crores of rupees to the consumers.Cyberabad and Nandigama police nabbed one Subhani Basha and recovered about e14 ICs, 8 displays, 3 GBR cables, one motherboard and one Hyundai i20 car.The main accused Basha, Babji Baba, Madasuguri Shankar and I.
