Dear Sajeev,
TR5 is remittance by cash directly to the office. This won't suit you. You can get the
RTI Rules on Kerala in the site "
sic.infokerala. Money can be remitted by various menas here; but nothing will suit you other than "By demand draft/banker's cheque /pay order payable to the SPIO.There is a Form No.3 given therein; but it isnot essential solong as your application contain all the informations like your address etc etc. You may address the application to the " State Public Information Officer, The Superintendent of Police, Ernakulam as suggested by Mr.Karira.. In case you need any other information on this kindly contact me.
