498a, 307 bail procedure

It is necessary to take the anticipatory bail, otherwise you will be arrested by the police .  

Thanks Jai Karan for ur comment on S. Gangadhar Gowda. I too find him really annoying. He doesn't seem to know the meaning of 'pro bono.'

Thanks for all. Its one of my friend issue. His wife filed 498a,dp3 and 4 on him yesterday. 307 not there. My friend and his famil is hiding in another town. 

Will police arrest them and send to judicial custody?. As per the supreme Court orders , police shouldn't arrest them right?.the complaint is strait forward like " in laws and husband harassing for dowry and no allegations like beating.". Total 5 members are in case. Please tell me how to get the bail ?
