The two men who allegedly beheaded the tailor in Rajasthan’s Udaipur have links to proscribed terror outfit ISIS, said the police sources. The police also said that the accused were part of a conspiracy to carry out serial blasts in Jaipur on March 30.

Through Pakistan-based Dawat-e-Islami, they were associated with Al-sufa, a remote sleeper organisation of ISIS. One of the two accused, Mohammad Riaz “Attari” was the head of Al-sufa in Udaipur. He was also associated with ISIS terrorist Mujeeb, who was arrested from Tonk earlier. Riaz is married and has two children.

Mujeeb, said the sources, was picked up from Rajasthan in a recently busted ISIS case.

Some individuals from Ratlam were arrested in Rajasthan and Madhya Pradesh in connection with the case, they said.

According to the sources, Riaz could even be an ISIS operative himself, as in his Facebook photos he can be seen using the typical finger signal used by Islamic State operatives across the world.

"We are investigating if he is a lone wolf," said the sources.
