420 bail and follow up

contracted cheated 10 lacks of my dad money without doing any work. only borewell is added which will cost only below 2 lack. h3 submitted a fake bill of 3.5 for borewell. So we cancelled his agreement and said return the balance amount. but he gave a overall bill of 10.5 lacks charging like vising charge per visit 5 thousand, bescom so and so... we lodged a cheating case on him. now my question is 1. is it possible to get anticipatory bail for him for this kind of cheating.? we have a empty site proof that he has not done any work. 2. is it possible for him to prove that whatever bill he gave is correct and escape from 420 case.? Thanks and Regards, Jothi
