Bangladesh's anti-crime elite force Rapid Action Battalion (RAB) have arrested four people including a pilot on charges of plotting sabotage with aircraft.
RAB spokesman Mufti Mahmud Khan confirmed the arrest of the militants of the banned Jamaatul Mujahideen Bangladesh (JMB) on Tuesday at a press briefing.
He said those arrested included Sabbir Amam, a co-pilot (first officer) of National flag-carrier Biman Bangladesh Airlines.
Khan said they were detained in a raid in the city on Monday night.
The JMB militants were hatching conspiracy to sabotage a plane.
JMB carried out a series of bombings in 63 out of the country's 64 districts, including capital Dhaka on Aug. 17, 2005, leaving two people dead and 150 others injured.
Hundreds of JMB leaders and activists were rounded up while six top leaders of the group, including Shaikh Abdur Rahman, were hanged in 2007.
Against the backdrop of a new wave of militancy rising, Bangladesh has stepped up anti-JMB drive aimed at dismantling all terrorist outfits and their networks in the country.
