The National Sea Rescue Institute is looking for a local hero, named Brandon, who helped save the lives of two people in Kalk Bay over the weekend.

The two men were swept out to sea on Saturday afternoon after a wave knocked them off the harbour wall.

A bystander, identified only as Brandon, jumped into the water with an NSRI pink rescue buoy to assist the men.

NSRI Simonstown station commander Simon McDonnell said duty crew were activated at 16h45 on Saturday, following reports of two men in the water.

They were reported to be swept out to sea through the harbour entrance, at Kalk Bay Harbour, and one man, identified only as Brandon had entered the water with an NSRI Pink Rescue Buoy to try to assist.

NSRI Simonstown launched the NSRI rescue craft Donna Nicholas while NSRI rescue swimmers, CMR (Cape Medical Response) and the City of Cape Town (CoCT) water rescue network were activated.

CoCT Law Enforcement officers, the SA Police Services, Cape Town Fire and Rescue Services, and WC Government Health EMS were alerted.

NSRI Strandfontein duty crew were also activated.

EMS Metro Control investigated the possibility to divert the EMS/AMS Skymed rescue helicopter, that was engaged on an unrelated routine mission, to respond to the emergency at Kalk Bay.

On arrival on the scene it was found that Good Samaritan Brandon had used an NSRI pink rescue buoy to assist the 2 men.

Brandon had got one man safely to shore where the casualty had been pulled out of the water with the assistance of bystanders.

Good Samaritan Brandon was assisting the second casualty in the water, using the NSRI pink rescue buoy to keep him afloat, but the casualty appeared to have suffered an injury preventing public members, using a ladder, to try to pull that man to safety.

Four NSRI rescue swimmers were then deployed into the water and they kitted Brandon out with a personal flotation device.

The NSRI says Brandon continued to assist rescue swimmers with the casualty on a ledge below the harbour pier.

On the NSRI rescue craft arriving on the scene a crane was used to hoist the casualty, secured into a specialised hoisting stretcher, onto the rescue craft and the casualty was brought safely to shore.

The injured man was taken into the care of CMR paramedics and he was transported to hospital by CMR ambulance in a serious but stable condition where he is recovering.

The NSRI has commended Brandon for his actions, appealing to him to come forward by calling 0823803800.

They have also called on members of the public to stay clear of Kalk Bay harbour wall during high tide when waves noticeably sweep over the harbour wall.
