The National Investigation Agency (NIA) on Saturday arrested key rightwing terror accused Dashrath Choudhary alias Rajendra Choudhary alias Samundar, the alleged bomb planter in Samjhauta Express train and Mecca Masjid of Hyderabad. He was arrested from Nagda in Ujjain district of MP.

In the initial interrogation, Rajendra has accepted that he planted improvised explosive devices (IEDs) in the Samjhauta train and Meeca Masjid in Hyderabad. He was active in RSS in Hatod of Madhya Pradesh.The arrest is perfectly timed as it comes in the middle of interior minister Rehman Malik's visit. Samunder, an accused named in the NIA chargesheet in the Samjhauta case, was carrying a Rs 5 lakh reward on his head.

His role was unraveled by another accused, Kamal Chauhan, who was arrested earlier this year in February. On February 18, 2007, a series of blasts ripped through Samjhauta Express near Panipat, Haryana, leading to the death of 68 people, most of them Pakistani nationals.

Earlier, a cell phone-triggered pipe bomb explosion inside Hyderabad's Mecca Masjid on May 18, 2007 left nine dead and 70 injured. Investigations also revealed, the chargesheet said, that all of them had undertaken training in handling of weapons and explosives in 2006 in a jungle near Bagli, Dewas district, Madhya Pradesh.
