The individuals contacted 111 and police tried to guide Loren out of the river, but unfortunately, the bank was very steep and he couldn't get out of it from the position he was in, Pretorius said.
Pretorius said his brother-in-law walked off into the distance, as per the police instructions, and they were going to meet him on the other side. However, that was the last sighting of him.
On Thursday, family and friends initiated their own search operation and kayaked the entire southbound river bed all the way through north through town to the area of the incident.
Since then, the team expanded the search and looked everywhere they could but to no avail, Pretorius said.
Ross-Taylor was last seen wearing a 2XL black t-shirt and camo shorts, had no shoes and left his keys, wallet, phone, and everything else behind. He weighs approximately 125-130 kgs, is 185 cm tall.
Pretorius urged anybody who saw Ross-Taylor or suspected it to be him to take a photo and send it to him on 0210481222 or alert number 105 for Loren Charles Ross-Taylor missing report.
