Police submitted the charge sheet to the third court of judicial magistrate against the accused Abdur Rahim alias Shahadat, 32, chief of Islam O Muslim, and former JMB's Rajshahi regional commander, and Selim alias Saifullah alias Harun Mistri, 26, chief military commander and mastermind of the outfit, former JMB's military commander Abdul Momin and Abdur Rakib alias Sumon, 28, of Chapainwabganj, Jalal Uddin alias Sagor, 38, of Naogaon and Hafez Sajedur Rahman alias Hanif of Bagmara.
Sub-Inspector Babul Akhtar of Bagmara Police Station has been investigating the affairs of Islam O Muslim for the last three months and charged them under sections 8, 9 and 10 of Anti-terrorism Ordinance 2008.
According to the charges, Selim and his brother-in-law Rafikul alias Jahangir were involved with JMB as they both were the disciples of executed JMB leader Siddikul Islam Bangla Bhai.
Rofikul maintained a JMB fund of Tk 1.70 lakh following the execution of its chief Shaikh Abdur Rahman, Bangla Bhai and five other top men.
Knowing it, Selim took the money from his sister (Rofikul's wife) and fled away.
Later, JMB's new commander of Rajshahi division Ashraf asked Selim to give back the money.
As he denied, the JMB men threatened him and his cohorts to kill at sight.
Then in March this year, Selim held two meetings with some 10 to 15 JMB men who also fled with JMB money and were on the run over threats on their lives.
Shahadat, Momin and other accused took part in the meetings at Gomostapur and Kansat in Chapainwabganj and they decided to run the new offshoot to counter the JMB threats.
At the meetings, Jalal and Sajedur were given the responsibility for organising the new offshoot at Bagmara upazila, says the charge sheet.
They decided to shift on small weaponry instead of bombs and grenades with an aim to reactivate and reorganise the inactive JMB men.
A special anti-militancy police team from Dhaka arrested four JMB militants including Momin and Sumon from Chapainwabganj in June.
Following their confessions, police and Rapid Action Battalion members arrested Shahadat, Selim and others from Gazipur, Rajshahi and Chapainawabganj in early July.
The law enforcement agencies also claimed that they were able to nip a 'dangerous outfit' in the bud as they retrieved a total 14 small arms and huge bullets from the arrestees.
Selim bought these small arms from India with the looted JMB fund and distributed those among the offshoot leaders.
A total of seven cases were lodged against them with Shibganj, Bholahat, Chapainawabganj sadar and Bagmara Police Stations.
With yesterday's charge sheet, the investigation into the affairs of Islam O Muslim came to an end, said sources.
