Mumbai, Oct. 7 -- The 33-year-old accountant was a reluctant witness in the ongoing trial of former RPF constable Chetan Singh Chaudhary, accused of shooting dead his senior and three visibly Muslim passengers on board the Jaipur-Mumbai Superfast Express in the early hours of July 31, 2023. He was so traumatised by what he had heard on the train that night that for a long time, he avoided long-distance train travel. When he did travel, he avoided using the washroom. On Monday though, the soft-spoken accountant managed to stick to his testimony at the Dindoshi Sessions Court despite defence counsel Jaywant Patil's relentless attempts to confuse him. His examination in chief by public prosecutor Sudhir Sapkale confirmed what previous witnesses had revealed about the shootout. The witness was woken up around 3am by an argument between three RPF personnel on escort duty. He heard one of them complain about feeling unwell and wanting to get off the train which had reached Surat. Another personnel, being addressed as 'Sir', told him that permission would have to be taken from senior officers before he could be allowed to get off. The man addressed as' Sir' then went out and on his return, told the man who had wanted to be relieved that senior officers had advised him to wait till the train reached Borivali and rest till then. He was also told to hand over his rifle to his colleague, the third RPF personnel present there. The witness then went back to sleep, but was again woken up by voices of the RPF personnel. He heard the man who had complained of being ill demanding that his rifle be returned to him. It was around 5am and the witness then went to the washroom, he said. While inside, he heard gunshots and someone shouting "Maar daala re". Afraid, he peeped out and saw the constable who had complained of being ill standing with his rifle. Below him on the floor, in a pool of blood, lay the man he had addressed as 'Sir'. The witness closed the door and remained inside the washroom for around two hours, not getting out even when the train stopped for a while between Mira Road and Dahisar. He opened the door only when the train reached Borivali. By then, blood had spread till the door of the washroom. A policeman helped him alight from the train. The witness' testimony could not be recorded on September 26 because Sapkale had been given additional charge of another court and was needed there....
