Imaginary happening on a train

I want to repeat what the apex court had earlier observed regarding detaining the ship and crew. Here is an imaginary situation.  Due to frequent thefts Government had employed armed guards in sleeper compartments for the safety of passengers. Early morning at about 3 am the train stopped in between. When the train was just starting a passenger hurriedly took one suitcase and hurried to the door and was getting down. One of the police man noticed it. The other police man was dozing. The alert police man thought that the person hurrying must be a thief and ran after him to catch him. Unfortunately when he was trying to catch him the person fell from the train. As the train had picked up speed the fall was fatal and he died of head injury. Later another passenger who was sitting near the person who was getting down told that he was a genuine passenger and was getting down as his house was near by. A case was filed against the police constable for causing the death of the passenger and he was arrested and sent to judicial custody. Now should the compartment detained at the nearest railway station along with the passengers till the case is over? Who will answer for the trouble the passengers will be having to stay in the compartment for months or years? Is it not the same case with Enrica Lexie? The railway compartment has no part in the incident and so the ship. The passengers are not involved in it and those who were awake and looking at the scuffle only just witnesses. So were the other crew . It is very illogical to detain the ship or put stringent conditions to release it.
