Being falsely implicated in a criminal case and feeling helpless now.

We are 5 friends A B C D & me and all are working in the Indian Army & I am just retired. One day A call me and told that we are going to my village which is nearby our military station at Kolkata by car you should also join. First I denied but after that he again called me and requested and I agreed and started for his village at 1900 hrs.

After reaching there he started quarelling with his neighbor and they 4 started beating the neighbor and after that all villagers crowded and they ran away. I was standing a little far and they cought me and beated me. After that the Police came & the next day my wife reached there and took my bail.

This case happened 1 year ago and still the chargesheet has not been put up and the main accused is Mr A. He also got bail because villagers know the main accused and another friend are safe now but my friend does not support me. One lawyer is handling this case and he paid for it but now he does not pay now I am alone. What should I do?
