Custody Room Escape

Yesterday, I have gone to meet my friend in the custody room. But he is not there. I am suspecting that police man who has arrested him for a wrong case. So, I want to check with my friend and also that idiot police man. By any means, I need the justice. So can anyone help me to escape from this custody room. Can you please find out the related objects and solve the puzzles to escape me from the custody room as soon as possible.
