But what offence you think he did for being jailed? is it a criminal related case or civil case? He wont be locked up and jailed if he didn't do anything against the Law or their Military Law?

However, this should undergo a due process after proven guilty, right? And what I can say right now, is nobody can help you here in QL especially in a case like this. Better yet, be in touch with his friends or some co-workers for any news about him.

Now, if you are quite sure that he is currently held up in the Central Prison, you can pay him a visit if you know the place? They have certain days and timing for visitors. And lastly, dont forget to pray for his wellness.
