The 19-year-old, who is gearing up for the 50m breaststroke on August 23, showed signs of lifting his favourite event by leading the pack in the 100m dash until the 70m mark at the Sugathadasa Indoor Stadium pool.

He, however, turned slow in the last hurdle allowing India's Sandeep Sejwal to win the gold in 1.07:73s.

Shajahan, who clocked 1.07:99s in the heats, finished the final with a timing of 1.08:08s to win the second silver for Bangladesh in the regional Olympic extravaganza.

His compatriot Niaz Ali finished third to win his second bronze in successive days. Niaz, who clinched the 200m breaststroke bronze on Saturday, finished the 100m in 1.10:34s.

"I started at BKSP in 1997 as a freestyle swimmer but changed to breaststroke in 2000," said Shahjahan.

The two-time 50m breaststroke national champion complained after the event that they have failed to improve personal timings because of the lack of minimum modern facilities like gym equipments.

"India and Sri Lanka get much more facilities than us but the result shows that we are not far behind in competition. If we had better facilities, we could have done better," said the boy from Chapainawabganj.

"We hope to do better in the short distance events and I am confident I will win gold in the 50m," he added.

Nazrul Islam won bronze in men's 50m freestyle while Sabura Khatun finished fifth among six swimmers in the women's 800m freestyle. Munmun Ahmed had the worst performance on the day, becoming last amongst seven competitors in the men's 200m backstroke. The women's 4x100m relay team (Sabura, Dolly, Mahfuza, Afsana) finished fourth among five teams.

Mizanur Rahman was the other Bangladeshi to win a bronze in weightlifting (77kg).
