False dowry case

An FIR has been lodged against me, my sister,my brother in law, my mother and father under 498a by my wife at her home town (Patna). The FIR says that all of us has beaten her and have not given food for days for dowry, even when in 3 years of marriage she hardly lived with them for 2-3 months. Although it is useless to say all the allegations are false as nowadays it is a fashion to file dowry case. Police called me 4 months back (December) and I asked them to send me a notice to get leave. However, it never came to me, so I didn't go. In feb I filed a divorce case for which they have not appeared for 2 hearings. Last week my parents and my sister got a call from police station saying you have to come to Patna and an arrest warrant is issued against me. I am in government service and if I get arrested I have heard that I can get suspended also. i talked to a lawyer and he told that the case is in court now. Besides, my sister and parents bail will be granted but mine most probably will get rejected. I may have to surrender and then apply for bail. What I should do to safeguard my self ? If I surrender, I can be arrested? Also, how long it will take to get the bail?
