Mohammed Omar Madni, a suspected aide of Lashkar-e-Toiba founder Hafiz Saeed, is likely to be questioned by the Mumbai police in connection with July 11, 2006 serial train blasts case.
"We are in touch with Delhi Police authorities and after getting more information from them, we will send a team to interrogate him," Additional Director General (Anti-Terrorism Squad) K P Raghuvanshi told PTI on Saturday.
The Delhi Police, while seeking Madni's custody, had said that he was found to have recruited Kamal Ansari, arrested by the ATS in connection with the train blasts that killed over 180 people.
Ansari is among the 13 arrested for their alleged involvement in planting the bombs aboard the suburban trains in Mumbai. The ATS has filed its chargesheet in the case.
Madni, arrested on Thursday, was allegedly looking to recruit new personnel for the Pakistan-based terror outfit and had knowledge about LeT operatives working out of Nepal.
He was allegedly in India to enrol youth from major cities for terror acts, police officials said.
