Arrested Lashkar commander Mohammad Omar Madni has been sent to police custody till June 19.
The 50-year-old Pakistani national, suspected to be a "key recruiter" for Lashkar-e-Toiba (LeT) in India and Nepal, was arrested from the national capital on Thursday evening, with officials seizing some currency, an identity card and driving license from him.
The Delhi Police have said that the arrested Pakistani national is an aide of Jamaat-ud-Dawa chief Hafiz Mohd Saeed.
Madni was caught by Delhi Police's Anti-Terror Wing 'Special Cell' near Qutub Minar in Mehrauli.
"We caught him this evening after receiving an input from intelligence agencies. He is a key operative of LeT in India and Nepal," Joint Commissioner of Police (Special Cell) P N Aggarwal said on Thursday.
He said they were interrogating Madni as the purpose of visit to India was not immediately known.
A senior police official said Madni was "one of the key persons" involved in recruitment for the LeT from the country and sending them for training in Pakistan by exploiting the "porous" Indo-Nepal border.
Asked about LeT operative's plans, the official said "The interrogation is on. We are not aware of his plans."
Police recovered $8,000, Rs 15,000 (Indian) and Rs 4,000 (Nepalese) besides an identity card and driving license.
"We have not recovered any explosive from him," the official said.
Police suspect that he came to the capital from Aligarh as a railway ticket from Aligarh to Delhi with Thursday's date was also recovered from him.
