Hi
1) Subsequent to the supreme court orders in Arnesh Kumar vs State Of Bihar & Anr on (2 July, 2014) , police cannot arrest the husband or his relatives in the event of a wife filing 498a or Domestic violence case.
2) The supreme court has mandated a 10 point formula that police need to comply prior to arresting the accused.
3) So technically police have to issue you a notice under Section 41(A), and you need to appear before the police after that. Police will arrest you only if you do not appear for investigation.
4) Since you have the DNA report and other proof to substantiate your claim that your wife is living in adultery, police will definitely not arrest you as it is apparent to the naked eye that your wife has filed false cases.
5) So get prepared with all your defenses and appear in front of the police officer along with a lawyer.
6) If you still are apprehensive of arrest, you can always move the high court under section 482 of cr.p.c and get the case quashed or in a worst case scenario get stay of arrest orders from the high court.
No worries at all as it is apparent that you have good grounds .
