Tarique Mohammad Saiful Islam, 35, assistant secretary general of Jamaat's Meherpur district unit, was killed as he tried to evade the police.
According to reports, police arrested Islam yesterday on charges of attacking police and leading the violent campaign ahead of January 5 elections. They carried out the raid at a village in the district in line with Islam's confession that fellow party men were holding a clandestine meeting there.
The report said as soon as the police reached the scene the Jamaat activists opened fire, triggering the gunfight when Islam tried to flee the scene and came in line of fire.
The death of the Jamaat's regional leader came two days after another activist of the party was killed during a gunfight with joint forces comprising paramilitary Border Guard Bangladesh (BGB) and police at north-western Nilphamari.
A crucial allay of Bangladesh Nationalist Party (BNP), Jamaat last year was barred from participating in the general elections by the Election Commission in line with a court order.
