I would recommend that you lodge a police complaint with the nearest police station, or alternatively if you feel threatened by her you may seek divorce; if you belong belong to Hindu faith, from the family court on the ground of cruelty and mental harassment.
Alternatively, after lodging a police complaint you may on the basis of the complaint approach court of sessions and seek interim anticipatory bail for 72 hours, in an event if a FIR is lodged by your wife. However, for ensuring anticipatory bail you would have to have certain evidences to convince the court that there exists "apprehension of arrest" from your wife lodging a false dowry case against you.
Thanks,
