Great Britain's Sam Hynd has cruised into the final of the S8 400m freestyle, with his brother Oliver next up in the pool.
The Brit took a strong lead from the start and gradually extended his length in the pool after a well-timed first turn.
Hynd continued his dominance and by the 200m mark the Brit was under no pressure from his competitors as he reached a comfortable lead.
Hynd recorded a time of 4:33.25, with China's Wang Yinan coming in second in a time of 4:37.86.
