When they reached the police station Mohan went to the person-in-charge (Station House Officer or S.H.O.) and told him what had happened. He also said that he wanted to give the complaint in writing. The S.H.O. rudely brushed him aside saying that he couldn’t be bothered to waste his time writing down minor complaints and then investigating them. Mohan showed him his injuries but the S.H.O. did not believe him.
Mohan was puzzled and did not know what to do. He was not sure why his complaint was not being recorded. He went and called his neighbours into the office.
They argued strongly that Mohan had been beaten up in front of them and had they not rescued him he would have been injured very seriously. They insisted that the case be registered. Finally, the officer agreed. He asked Mohan to write down his complaint and also told the people that he would send a constable the next day to investigate the incident.
Question Box :
(i) Show the above situation in the police station through a skit.
(ii) Then talk about how you felt playing Mohan’s role or that of the S.H.O. or the neighbours.
(iii) Could the S.H.O. have handled the situation differently ?
