According to the police headquarters, some 159 cases were lodged at different police stations across the country in connection with the bombings.
In the last 17 years, trials in 94 cases have already been disposed of in which 334 people were sentenced to different jail terms while 55 cases are still under trial, the sources said.
Twenty-seven accused in the serial blasts had been handed down capital punishment and eight of them were hanged.
The JMB tried to showcase its existence to the nation by carrying out the blasts. But their organisational activities suffered a huge setback with the execution of JMB’s top six leaders in 2007.
The six leaders- Shaikh Abdur Rahman, his second-in-command Siddiqul Islam Bangla Bhai, military commander Ataur Rahman Sunny, think-tank members Abdul Awal, Khaled Saifullah and Salahuddin -- were hanged on 30 March in 2007 for killing two judges in Jhalokathi district.
