It is Shakil who supplied the explosives which were used in killing two judges in Jhalakathi on November 14 last year.

Before his death, suicide bomber Hasan Al Mamun who killed the two judges -- Jagannath Pandey and Sohel Ahmed -- in Jhalakathi, disclosed Shakil's name in his confessional statement

In the charge sheet of the two judges killing case, Shakil alias Molla Omar was described as JMB's explosives expert who made and delivered the bombs to Mamun and trained him about its explosion mechanism.

Barisal Speedy Trial Tribunal on February 20 awarded 40 years rigorous imprisonment to Shakil, JMB chief Abdur Rahman, Siddiqul Islam alias Bangla Bhai, Abdul Awal, Ataur Rshman Sunny, Khaled Saifullah and Mamun.

Shakil also visited Barisal in mid October 2005 along with Abdur Rahman, Bangla Bhai, Awal, Sunny, Khalid, Mamun and participated in the assassination plot-making meeting and then supplied the bombs to Mamun, the killer, at Jhalakathi.

Rab said they were searching for one of JMB's bomb experts named Shakil in Naogaon after the August 17 countrywide bomb blasts.

"We later got information that Shakil works for the JMB in Pabna, Comilla, Sirajganj and Kushtia districts," said a Rab officer.

Meanwhile, a Rab officer said it is still to be confirmed whether the Shakil who introduced himself as Mollah Omar is that Shakil.
