At least 12 suspected Jaish-e-Mohammed ​(JeM) terrorists were on Wednesday morning arrested during a raid by the Intelligence Bureau and Delhi police special cell.

The police have detained suspects from Delhi, NCR region and Deoband in Uttar Pradesh.

According to reports, eight people have been arrested from Delhi, while four of them were picked up from Deoband.

"Bomb making materials were seized from the 12 suspected JeM Terrorists, they are presently being questioned by police," reported ANI quoting sources.

"While a team of the force's anti-terror unit Special Cell zeroed in on two of the youths, while they were allegedly in the process of making improvised explosive device, from east Delhi's Gokulpuri area, names of the others emerged during their questioning and they were tracked down one after another in the wee hours today, a senior official told PTI.

All of them are suspected to be members of a sleeper unit of a terror outfit, planning an attack in the national capital and other cities, the official said.

According to TOI, the special cell has registered an FIR against the suspects for being members of an unlawful group (Unlawful Activities and Prevention Act, UAPA) and under the Explosives Act and for criminal conspiracy.

"On interrogation it was found that they had been in touch with JeM leader Yousuf Al Hindi, and also claimed to be the terror outfit's activists themselves," said news18.com.

Special Cell teams are conducting raids in Delhi and UP, and several arrests are likely in the next 24 hours.​
