How does party "A" get back his company in fastest way

1). Party "A" Real owner of the company (who lives in another city). 2). Party "A" knows Party "B" from 2017 through a broker, not before 2017. 3). The market value of the Party "A" company is around "RS.5 CR" for "2100 sq.mt" plot area, of MIDC Nasik. 4). Party "B" purchaser (MOU made betn Party "A" & Party "B" in year 2017). 5). Party "B" made a forged Notorised POA dated 2012 (Photo of the owner Party "A", with forged signature & Thumb impression). 6). Party "B" opened a forged Current Account in Co- Operative bank in the name of Party "A" Real owners company. 7). Party "B" sold the company on the bases of Forged Notorised POA dated 2012 to Party "C". (Settled price RS. 2.10 CR, betn Party "B" & Party "C"). 8). Whereas Party "C" too had a Plot in the same MIDC Nasik "1000 sq.mt", which he sold for "RS. 2.7 CR". 9). Party "C" has made 70% payment to Party "B" in the name of Party "A" company's name, but the payment has gone to the forged company's account & not the real owners Nationalised bank account. 10). Party "B" has given the possession of the company to Party "C" without the knowledge of Real Owner Party "A", whereas all important documents, all Machineries of Party "A" & Household materials are in the Company. 12). FIR was lodged on Party "B" & Party "C", after it came to the knowledge of the Real Owner "A". 13). B4 lodging an FIR, we approached the CP of Nasik, who ordered the PI of the concerned police station to look into the matter & report the same. 14). The PI took the initiative & called the party "C" with the documents of the deal betn party "B" & party "C", after going through the documents produced by party "C" to the PI, it was confirmed that the documents are fraud & asked party "C", before paying 70%, Questions asked by "PI" to party "C" (a). Why you did not Authenticate the documents produced which is an POA, given to an outsider & not a family member ?, (b). Why didn't he insist on meeting the Real Owner party "A" ?, (c). Why he did not give a Newspaper Notice after the Token Amount ? These are General Practice by a Purchaser. 15). Party "C", then agreed Verbally in front of PI, that he is at Fault & he is ready to Hand Over the Company Premises to party "A" the Real Owner. 16). Next day party "C" hands over the Company to Party "A" Real Owner. Party "A" appoints a Security Guard & party "C" requested to party "A", to give him 2 to 3 days time for shifting his Machineries & Documents. Party "A" agreed in Humanitarian grounds & police too is involved. 17). On the 3rd day the party "C" took a "U" turn, kicked off my Security Guard & took back the position of the Company. 18). Party "A" got to know, that the party "C" advocate & PI personal work advocate are the same, & after party "C" took back the position of the company, the PI approach towards party "A" became different & did not take appropriate action against party "C" & started insisting that police has no role in giving the possession.
