Detention/Judicial Custody is Questioned

Sir I have been booked by area Police Station u/s 384, 506 of IPC in July 2016 and the concerned IO issued 41 (a) notice after 6 months from the institution of the case/registration of FIR. Upon receipt of 41(a) Notice a suitable written reply send to IO/SHO by registered post referring Order of the Hon'ble Supreme Court - CrPc Amendment of 41(a) - Naresh Kumar Vs State of Bihar which stipulates that, Notice u/s 41(a) to be issued to the accused within 15 days from the date of the institution of the case/FIR and within 30 days by DSP and not beyond 30 days. Later I have been arrested and sent to Judicial Custody for 14 Days and my 3 bail petitions were dismissed. However, the allegation is that, I have demanded Extortion Money of Rs. 35 Lacks from the Shop Owner to vacate the shop worth of Rs. 28 Lacks (Market Value). Please guide what action can I take against the Police Officer/(s) and shall I move to High Court at this stage challenging FIR itself before the Charge Sheet is filed.
