New Delhi : The Supreme Court today issued notice to the Rajasthan Government and sought a detailed reply within four weeks in connection with the issue of removing of mobile towers within a distance of 500 metres from the prisons in the State. A vacation bench of the apex court, headed by Justice Arjan Kumar Sikri and also comprising Justice Deepak Gupta, sought a reply from the Rajasthan Government within four weeks on the issue. The Rajasthan Government had directed to remove all mobile towers within a distance of 500 metres of all the prisons from June 8. The Cellular Operators Association of India (COAI), the association of the telecom body, had knocked the doors of the apex court challenging the order which had sought removal of many mobile towers located within 500-metre distance from the jails in the State. The COAI, in its plea, claimed that there were around 400 base transceiver stations and they provided services to approximately 80-lakh people across the State and if these mobile phone towers were removed, the quality of service would be severely and seriously affected. "Therefore, they should not be sealed or removed," the COAI in its plea had argued before the apex court.
