Islamic State (IS), had also tried to get a foothold in India first through Uttar Pradesh in 2016-17, reported Economic Times on. In May 2016 a purported IS video showed jihadists supposedly from India threatening to "return" to "avenge killing of Muslims in India". Two Indian Mujahideen (IM) operatives, Abu Rashid Ahmad and Mohammad 'Bada' Sajid from Uttar Pradesh's Azamgarh District were identified amongst those featured in this video. The release of this video led the then Union Ministry of Home Affairs (UMHA) to intervene in the matter, announcing that the Centre was taking all steps to tackle the issue. The cause of concern for the Uttar Pradesh Police stemmed from arrest of two UP youths, Shakir and Rizwan, who were in touch with the IS through its social media network. Shakir was arrested by the Delhi Police on May 4, 2016 from Deoband in Saharanapur District for his alleged links with Jaish-e-Mohammed (JEM) while Rizwan was held by the Mumbai Police from Kushinagar District in Uttar Pradesh on January 23, 2016. In March, 2017, investigators unearthed a suspected IS terror module operating in India. Ghaus Mohammed Khan, an ex-Indian Air Force officer, was the leader of the group planning attacks in the country. The Uttar Pradesh ATS on March 7, 2017 managed to kill a terrorist hiding inside a house in Thakurganj area of Lucknow. Uttar Pradesh ATS Inspector General Aseem Arun revealed that the neutralised terrorist was a member of the IS of Khorasan module. Terror suspects Atif and Danish were arrested in Lucknow by the NIA in connection with the Lucknow terror operation. The NIA then registered a First Information Report (FIR) in the IS- inspired cases in the Madhya Pradesh and Lucknow (Uttar Pradesh) terror operations.
