Shakeel was arrested from near Lucknow by a team of Delhi Police's Special Cell, a senior police official said.
He is allegedly into brainwashing and motivating youth to join the terror outfit, which is named in several serial blasts in the country, the official said.
Shakeel is said to be a close relative of Bashir, another suspected terrorist who was arrested by Delhi Police.
This is the fourth arrest of an Indian Mujahideen terrorist by Delhi Police this year. In November last year, Delhi Police had arrested six Indian Mujahideen terrorists from across the country.
On March 26, police had arrested Assadullah Rehman alias Dilkash (20), an alleged aide of the outfit's elusive chief operative Yasin Bhatkal, from north-east Delhi's Karawal Nagar with one kg explosives and a detonator.
Dilkash, who hails from Darbanga in Bihar, had allegedly escaped in November last year from the arms factory run by Indian Mujahideen in west Delhi's Nangloi before the police crackdown during which a number of suspected terrorists were nabbed by police.
In April last year, the official said, on instructions from Bhatkal, he reached Delhi and was taken to the factory at Meer Vihar in Nangloi which was later busted by police.
After the arrests of Indian Mujahideen operatives in November last, Bhatkal directed him to leave the factory premises along with whatever explosives and other material he could lay his hands on. MORE
