NEW DELHI: Delhi Chief Minister Arvind Kejriwal has been fighting a vociferous battle – through radio spots — with the Centre for handing over control of police to Delhi government . But information accessed under Right to Information Act has revealed that Kejriwal has not written a single letter to the Centre on the issue.Applications filed by RTI activist Dev Ashish Bhattacharya have revealed that not a single letter has been sent by Kejriwal, chief minister's office or the offices of his entire Cabinet to the Home Ministry – the nodal ministry for law and order issues – for handing over the control of Delhi Police to the state government. Bhattacharya had filed an application with Home Ministry in April. The Home Ministry said no such letter had been received from the chief minister. The ministry transferred the application to chief minister's office and Delhi Police. Replies under RTI received from Kejriwal's office, Delhi's home department and the offices of his Cabinet colleagues say there is no such correspondence.The application was filed after Turkman Gate road rage case where a man was beaten to death in front of his children and a farmer's alleged suicide at an AAP rally at Jantar Mantar. The replies from different public authorities were received last week and said that Delhi government had not even written letters to expedite probes in the two cases.After a gruesome murder case in Anand Parbat where a girl was stabbed multiple times last month, Kejriwal had started a media campaign seeking control over Delhi Police. In a radio advertisement, he had appealed directly to Modi addressing him as "Sir" and seeking his intervention.Speaking to ET, Bhattacharya pointed out, "The replies show that Kejriwal has not written any letter to formally seek control over Delhi Police. It makes one wonder if all the advertisements in the media are just to carry on a blame game and not seriously address such an issue."
