One of the main conditions imposed on grant of bail is that the accused on bail will not threaten the witnesses. In this case, you have said that the accused is trying to threaten you to force you for compromising the case. If you have evidence of such threats, then it may become a fit case for cancellation of bail granted to the accused.
Yes, you as a victim (and, it appears that you are also the complainant) can file an application before the court which granted the bail, for cancellation of bail. You may engage a private advocate for this purpose. You’ll also have to make the State also a party (through the police station concerned).
At the same time, it may be advisable to convince the police to file such an application since that may perhaps carry more weight. If the local police station is not helping you in this regard, you can complain to the senior officers of police.
