Bail for Section 302,380,307

My brother visited his friend H for firecracker factory enquiry and stayed in his home(a town in TN) from Bangalore for one day, reached in morning and left in evening the same say. H's wife went to a beauty parlor in afternoon and my brother picked her up along with his friend(her husband) and dropped them at their relatives place and came back. After 2 days my brother was picked up by Police without in uniform and we were told that he is prime suspect in murder. But my brother's name is not mentioned in FIR not even he is referenced anywhere. He was taken in custody based on the confession by H(my brother's friend) and his wife. They were beaten and torchered for 2 days to confess; scared my brother confessed without even doing anything, Police told him a story and he said yes he has done that. Now after 30 days we applied for a bail which got rejected, my question is; is there any way to get him out on bail before chargesheet is filed or if we can ask police to submit the chargesheet at the earliest. Session Court : Thoothukudi We are north Indians working in IT and do not understand Tamil at all and it does not help. We are desperate for him to atleast come out of the jail. Please suggest any option.
