It is not possible for us to help you on detailed facts of your case without having seen the detailed documents of your case (please see policy guidelines of this Forum). Only a lawyer who has actually seen full detailed facts of your case can guide you on facts of the case. So, please engage some lawyer, preferably a local lawyer, to handle your case for discharge petition and/or for trial.
Also, looking at the sections with which you have been charged (420, 424, 467, 468, 471, 201 & 120B IPC), some of such sections have maximum punishment of life imprisonment (such as Section 467 IPC). Therefore, police has the power to arrest without warrant in such cases.
Further, please also note that Section 48 of the Criminal Procedure permits a police officer having the power / authorisation to arrest, to make arrest even outside his jurisdiction anywhere in India. This section is reproduced below for your information:
“48. Pursuit of offenders into other jurisdictions.— A police officer may, for the purpose of arresting without warrant any person whom he is authorised to arrest, pursue such person into any place in India.”
Likewise, a police officer conducting investigation into a cognizable offence (like the one against you) can conduct investigation at any place in India.
