Rinto, son of late Abdul Khaleque Khan, founder-chairman of Opsonin Group of Industries and a promising artiste, had come to the capital from his Barisal town residence to lead a cultural group for rendering a musical soiree.

Rinto, who was also a close friend of the second son of Shaheed Abdur Rob Serniabat, the then cabinet minister, went to his friend's residence on that fateful night and a bullet of the assassins put an end to his life.

In observance of the death anniversary of Rinto, a milad mahfil and special prayer was organised at the Eskaton head office of the Opsonin Group.

Besides, the staff members of the company, relatives and admirers of the deceased, including political leaders, cultural activists and dignitaries attended the mahfil.
