Keung To, a member of the local boy band Mirror, fell into the sea when he was out jogging on Tuesday afternoon, according to the singer's agency.

Police said officers responded to a report of a person found in waters off Man Fai Street in Central at around 4.30pm.

Officers said the man was later rescued by boat and taken to Queen Mary Hospital for treatment.

Makerville, Keung's agency, said in a statement that the singer felt dizzy while jogging.

"Keung To is currently resting in the hospital. There aren't any major concerns. We would like to thank everyone who helped in the accident. Sorry for making everyone worry," it said.

Keung's manager, Ahfa Wong, also posted on Instagram on the singer's behalf.

"It was just a small accident due to my own carelessness. I am fine. Please do not worry. I hope there won't be any speculation," he was quoted as saying.

"I am truly sorry for making people worried."
