Cross fir

My father was govt servant rtd on 31-05-17,was attacked along with 5 other employees while on duty during inspection work of school by some local land mafia who were holding govt land illegally,then my father lodge fir against local land mafia and case was charge sheeted under ipc 147,148,308,332,353,504,506,307,7cla,325 and after few days mafia registered cross fir against my father and 5 others under ipc147,148,323,504 and police made chargesheet against govt employees,now i am asking police to send this chargesheet to court so that we can settle this issue(compromise) but police is saying that we have to take permission from ur father"s govt department without this police cant submit in court(and permission is pending since one year,its time taking process),my ques is my father has not given statement in court as both parties want compromise and BW was issued against my father to give statement and fear is that if my father gives statement in favour of mafia they may create problem to us as the crossfire case is still pending with police and some day after some years this crossfire case will rise up again and we may face problems,please guide us what to do?
