Fearing outbreaks of religious violence, police in the Indian state of Rajasthan banned public gatherings and suspended internet services a day after two Muslims posted a video claiming responsibility for killing a Hindu tailor in the city of Udaipur. Two suspects were being interrogated by federal investigators on Wednesday, while state police were on guard against any unrest in the north-western state. “We are under strict orders to prevent any form of protests or demonstrations scheduled to condemn the murder,” Hawa Singh Ghumaria, a senior police officer in Rajasthan, told Reuters, adding that the crime had sent “shock waves through the country’’. Brandishing a meat cleaver, two bearded men said in the video that they were avenging an insult to the prophet Mohammed caused by the victim. They also alluded to Nupur Sharma, a former spokesperson for the ruling Hindu nationalist Bharatiya Janata Party (BJP), whose remarks about the prophet earlier this month triggered domestic and international outrage. India’s home minister, Amit Shah, said in a tweet that federal police had taken over the investigation into “the brutal murder” of Kanhaiya Lal Teli, giving the victim’s full name. “The involvement of any organization and international links will be thoroughly investigated,” Shah said. Late on Wednesday, a spokesperson from Pakistan’s foreign ministry rejected reports in some Indian media that linked the suspects to a Pakistan-based organization. The two assailants had slashed Teli’s head and throat in an attack while the tailor was taking measurements, according to Bhawarlal Thoda, a city administrator in Udaipur. According to Thoda, the tailor had been detained over a social media post in support of the BJP spokesperson that was traced to his mobile telephone, and after being released Teli had told police on 15 June that he was being threatened by some group. “Terrorists executed my father in the most shocking way, the country must stand with our family to demand justice,” the victim’s son, Yash, told Reuters after his father’s body was cremated on Wednesday. He said the culprits should be tried and sentenced to death and denied that his father has made any remarks that would be offensive to other religions. “The incident has shocked followers of Islam, the heinous act committed by two men is absolutely un-Islamic,” said Maulana Ahmed Siddiqui, a Muslim cleric based in Udaipur. Authorities said they had suspended internet services in several parts of Rajasthan to prevent the circulation of the video. “The mood is tense and almost all shops are closed today,” Thoda said. The city of about half a million people is one of the major tourists draws in the desert state, and is known for its luxurious hotels, including the well-known Taj Lake Palace. In another video clip posted online, one of the assailants also went on to threaten the prime minister, Narendra Modi, saying their blade would find him too. The federal government late on Wednesday asked social media platforms to immediately remove content that encourages, glorifies, or justifies the killing. The Ministry of Electronics and Information Technology said in a notice that the removal was necessary “to prevent any incitement and disruption of public order and to restore public peace and harmony”. Hardline Hindu organizations held protests in the capital, New Delhi, to condemn the killing of Teli, and more protests were planned on Thursday. India has a long history of religious violence, and thousands of people have been killed since the country became independent from British colonial rule in 1947. Modi’s pursuit of a “Hindu first” agenda since coming to power in 2014 has stoked tensions in a country where Muslims make up about 13% of its 1.4 billion people. Earlier this month the BJP suspended Sharma from the party and expelled another official but the furor has not died down. Modi has not commented on the incident in Udaipur. But former Rajasthan chief minister Vasundhara Raje, who belongs to the BJP, blamed the Congress Party, now running the state, for the “communal frenzy and violence” that has arisen there. Raje said, “such acts can occur because the state government provides tacit support to criminals.“ While Congress has championed secular values in India since independence, the BJP has cast it as a pro-Muslim party in order to draw Hindus away from its main opposition. Rajasthan, with a population of about 69 million people, is just one of two Indian states where Congress holds a majority in the state legislature and it is due to hold elections next year.
