Accused not tradable

I have non balable warrent against two accused for 138 cheque bounce . I also visited his office home in Patna along with Pune polish officer but they are not traceable and their family members r not telling their current location . Accused live in Patna and is often goes to Delhi and London and hide their when some one comes for asking due money or any thing . Both accused have running from one state to other like Bihar to Delhi and London . It is very difficult to take polish officer from Pune to different states every time and they ask for lots of money for doing this job as every officer do so . I am asking u to help me in this case and what should I do to recover my money . They have business in Patna and Delhi and their managers are handling these business and they don't face any financial problem . I am only spending money for arresting and ruining long duration 138 criminal case . What should I do . Can't I cancel accuses UK visa because they are required in India for case and how to take local polish officers help in Patna and Delhi to catch them .???,,
