The family of a drowning victim is giving lifesaving organizations in the United Kingdom access to surveillance footage of the tragic event.

In 2016, Anthony Cleon Grant was swimming at a leisure center in London when suffered a cardiac arrest and sank to the bottom of the pool. He remained there for more than five minutes before someone alerted a lifeguard on duty. The guard tried to resuscitate him, but was unsuccessful.

The coroner’s investigation into his death concluded that the event could have been prevented.

In a recent report to the Royal Life Saving Society and the facility’s management company, Coroner ME Hassell noted that rotations could have been more frequent; there could have been more than one lifeguard poolside; and an underwater drowning detection system could have alerted staff sooner.

She also recommended that the industry consider reviewing the CCTV footage to learn how this event could have been avoided.

“I write to you specifically because Mr. Grant’s family have given their consent for me to forward to you the footage of the pool CCTV from the time when he first got into difficulty to the end of the attempted rescue, in the hope that you will be able to make this, or at least part of this, nationally available as a training tool,” she advised.

It’s not clear what RLSS will do with the video.

“It’s playing a part in our ongoing review of all the details and recommendations, raised by the inquest,” said Vicki Hartley-Kite, RLSS UK spokesperson.
