A security guard for the Indian railways has been detained after it is claimed that he opened fire on an express train between Mumbai and Jaipur, killing four passengers. Here is what to know about the incident:

What happened on the train?

The accused was identified as Chetan Singh, a constable in India’s Railway Protection Force (RPF), according to police. The 33-year-old early on Monday allegedly used his service rifle to fatally shoot four people on the Jaipur-Mumbai Central Superfast Express. He fired 12 rounds from the automatic weapon, reports in Indian media said. The suspect first allegedly shot at his senior colleague, RPF Assistant Sub-Inspector Tikaram Meena. Some reports said the incident took place after a heated argument between the two took a communal turn, but this could not be independently confirmed. The accused then allegedly opened fire at a passenger who was in the same compartment, according to the Indian Express. Singh later crossed into two separate coaches where he allegedly killed two other passengers. He then tried to stop the train and got off near Borivali, a town in Maharashtra state, where he was apprehended by police.

Who is the main accused?

Singh is a constable, a lower-grade security official, in the RPF from Hathras in Uttar Pradesh, the most populous state in India. RPF officers board trains on escort duty in order to provide safety and security to the passengers.

What did the accused say?

Following the shooting, a video posted on social media and verified by Al Jazeera purportedly showed Singh holding a rifle and standing next to a blood-soaked body of a bearded man. The man in the video is then heard saying: “They were being operated from Pakistan and our media is giving [them] coverage. They are all aware. But I am telling you, if you want to live and vote in Hindustan [India] – it is only [Prime Minister Narendra] Modi and [Uttar Pradesh Chief Minister Adityanath] Yogi, these are the only two names.”

Who are the victims?

Meena, a 57-year-old man from Sawai Madhoper village in Rajasthan state, was due to retire soon from the RPF after 33 years of service, reports said. Indian media also reported that the other three victims were identified by police as Abdul Kadar, 64, Asgar Abbas Ali, 48 and Syed Saifullah. They were all reported to be Muslim. Ali, a bangle seller, was the last man to be allegedly shot by Singh.

What have officials said?

Divisional Railway Manager Niraj Verma told reporters in Mumbai that they received information about the incident at 6am on Monday (00:30 GMT). “He was taken away to a police station, where he is being held,” he said, referring to the suspect. A railway official dismissed reports saying said that Singh had fired the shots after a communal argument, adding that the accused “wasn’t feeling well and hence lost his calm”. “He had a short fuse. He was quite hot-headed. There was no altercation. He just lost his temper and shot his senior, then fired at whoever he saw,” Praveen Sinha, inspector general of RPF (Western Railway), was quoted as saying by ANI. A legislator of Modi’s Bharatiya Janata Party from Maharashtra called for a thorough investigation. Manisha Chaudhary said an inquiry “must be carried out to ascertain the exact reason behind the incident”, the Indian Express reported. Modi has not reacted to the incident yet. He was in Maharashtra’s second most populous city of Pune on Tuesday, where he was conferred with an award. He also inaugurated a metro train project in the city.

What happens next?

Police have opened an investigation. Surendra Landge, a lawyer representing Singh, said he met the accused briefly on Tuesday. “He told me he is innocent and has no knowledge about the firing [incident],” Landge told India’s PTI news agency. “A senior railway official told the court that there should be an inquiry and medical checkup to ascertain Singh’s mental condition,” he added. The lawyer said police officials in the suspect’s hometown should meet members of his family as part of the investigation to find out more.

What has been the reaction?

The fatal shooting has been condemned on social media with a senior leader from the opposition Indian National Congress party, Jairam Ramesh, calling it a “cold-blooded murder”. “The genie of hate is now out of the bottle and it will take a lot of collective effort to put it back in,” Ramesh said in a tweet. He laid the blame for “hate and violence” on the BJP and said its top leaders were “complicit in damaging the social fabric of India”. Asaduddin Owaisi, a Muslim member of parliament and leader of the All India Majlis-e-Ittehad-ul-Muslimeen (AIMIM) party which advocates for the rights of Muslims and other marginalised groups, called it a “terror attack that specifically targeted Muslims”. Some social media users have reported that their posts on X, formerly known as Twitter, have been withheld by the platform after complaints from the Indian government. SOURCE: AL JAZEERA
