498A filed against my brother and parents after almost 6 years of marraige and 1 year of separation.

Hello Sir, This is regarding my Brother. He was married during 24/JAN/2013. Till 2017 my brother and wife were staying together and have a daughter during 2015. She also belonged to the same town as us [Berhampore]. During AUG/2016 citing character mismatch his wife walked out from the house to her own parents home, along with their daughter. Since the reason appeared vague and my brother assumed she to be returning back, he kept staying in the same house. Thereafter when she torn all contacts and didn't return back, my brother decided to shift to a rented house in the same town, after around a month. To note: the earlier house where they were staying was in the same hospital complex, which is owned by her father. Thereafter on 09/OCT/2018, she filed for 498A along with 307 against my brother, father and mother. We had not received any intimation of the same earlier. Today [21/NOV/2018] police officer visited our house and informed about the same and asked to take bail to avoid arrest. Kindly suggest what would be the best possible way to proceed. We are already in contact with lawyer to arrange for the bail tomorrow. Note: My parents used to stay in our own house all through with intermittent visits from both sides. Regards, Rupam Banerjee.
