A 55-year-old crew member of a sand-laden vessel went missing after it sank following a collision with a launch in the Meghna river off the coast of Charkishoregnj in Munsiganj on Wednesday night.
The man was identified as Motaleb Miji, son of Rafijul Huq Miji, from Bhola.
River police and local people said the ill-fated vessel, Makam-3, with six crew members on board, capsized in the river after being hit by the Barishal-bound MV Surovi-7 launch around 11pm.

Motaleb Miji could not get out of the sunken vessel and remained missing since then, said another crew member named Sabuj.
MV Surovi-7 was anchored after the accident and the passengers of the launch were unhurt, he added.
Kolagacchia river police barrack sources said that the coast guard and fire service were trying to rescue the missing crew member.
Humayun Kabir Molla, the manager of MV Suravi-7, filed a case in this regard on Thursday.
