Bangladeshi swimmer Sonia Khatun finished 64th among 79 competitors in the heats of the 50m freestyle event of the Olympic Games at the Paris La Defense Arena today.

The 25-year-old was way off her personal best mark of 30.11 seconds, which she had set in the Asian Games in China last year.

The top 16 swimmers from the heats made it to the semifinals, with the 16th qualifier clocking 24.72 seconds.

With Sonia's event, Bangladesh's sorry campaign in the Summer Games this year came to and, with all five participants disappointing big time.
