A 30-year-old engineer, who was allegedly part of a terrorist conspiracy to target the Capital during the upcoming festival season in addition to being involved the Pune serial blasts, was arrested by the special cell, police said on Wednesday.
Landge Irfan Mustafa, who hails from Maharashtra's Ahmednagar, was arrested from a bus stand in Jaipur on October 10.
He allegedly belongs to the home-grown terror outfit Indian Mujahideen's (IM) 'Maharashtra Module' and was in direct touch with IM boss Riyaz Bhatkal.
"Irfan's role came to light during the interrogation of the three other IM operatives, arrested by the Special Cell for executing the Pune serial blasts, recently," said SN Shrivastava, special commissioner of police (special cell).
A Delhi court on Wednesday extended by 10 days the police custody of the three suspected IM operatives.
According to sources, apart from being the fourth IM operative tasked with executing a terror bid similar to Pune's in Delhi, Irfan, who has worked as an Autocad Engineer between January 2008 and June 2009, was the "logistical brain behind the Pune operation".
Police also claimed he was passing on instructions about possible hideouts to the module's two absconding members, Shakir and Ahmad, after their associates Asad Khan, 33, Imran Khan, 31 and Syed Feroze, 38, were nabbed between late September and early October.
"This July, Riyaz Bhatkal instructed Irfan to arrange a rented accommodation in Pune and subsequently, he and Feroze managed to find a rented house at Kasarwadi without submitting any document or ID," Shrivastava said.
"Irfan then received two people, who later turned out to be Shakir and Ahmad, one of whom he had met in Pune last November. He took them to the rented house where they provided him a list of various electronic items for making Improvised Explosive Devices (IEDs) purchased from Pune. He was also involved in making of the IEDs."
Police said Irfan also used to receive hawala money for 'terrorist activity' from Riyaz Bhatkal, who had also instructed him to buy two pistols and give them to Imran.
In July 2007, according to police, Irfan's younger sister Gohar got married to Asad Khan whom he later introduced to Imran.
"In September, 2007, Asad went for 'khidmat' to Saudi Arabia and Imran Khan did the same in 2008. There the two men came in contact with Fayaz Qagzi, the Lashkar-e-Taiba (LeT) commander who provided his e-mail IDs to them to get in touch with him," said Shrivastava.
"In 2010, during his second trip to Mecca, he established contact with Fayaz Kagzi who showed interest in him just as he had with Asad and Imran."
