Mumbai: Malegaon blast accused Lokesh Sharma on Monday approached the Bombay High Court challenging a special court's order remanding him in the custody of National Investigation Agency (NIA).

"The NIA has not even shown to have formally arrested Lokesh in the Malegaon case... then how can they take his custody and question him. He (Lokesh) is being tortured at the NIA headquarters in Delhi where he is lodged. The agency is trying to forcibly take his confession," Lokesh's lawyer Ganesh Sovani argued before the court.

A division bench of justices V M Kanade and P D Kode has posted the matter for hearing on March 7.

The NIA had taken Lokesh's custody from the Panchkula court, where he was in judicial custody in connection with the Samjhauta train bombing case, and produced him before special MCOCA court here on February 27. Lokesh was then remanded in NIA custody till March 9.

The agency had sought Lokesh's custody to question him in connection with the September 29, 2008 Malegaon blast in which six people were killed.

Sharma, a close associate of Sunil Joshi (the suspected 'mastermind' behind the blasts who was later murdered), allegedly also planted a bomb on Samjhauta Express.

The name of Lokesh, who hails from Indore, had cropped up in Ajmer and Mecca Masjid blasts of Hyderabad. He was arrested on June 17, 2010 for the Ajmer blasts and on June 18, 2011 for Samjhauta blasts where the probe agency alleged that he was also one of the suspects who planted the bomb.
