An 11-year-old boy from Wisbech has been hailed a hero after he saved a toddler from drowning in a swimming pool in Thetford.

Derren Singleton pulled the three-year-old boy to safety after noticing him at the bottom of the pool.

“I cannot believe that the lifeguards didn’t see what was going on,” Derren’s dad, Daniel, told KL.FM.

“I’m really proud of Derren. He acted on his instincts to go down and get him; he wasn’t worried about what could have happened to himself. It’s really good.”

Derren pulled the young boy above the water, and his father found him with the child in his arms.

“His parents weren’t even in the pool,” Daniel added. “He was under about five feet of water on his own.”

The young boy was eventually reunited with his parents.
