Detectives are following up on all leads and "working around the clock" to find Cape Town businessman Liyaqat Parker, after he was allegedly kidnapped outside his work premises in N1 City.
Experts were combing the area where he was last seen for clues, said Western Cape police spokesperson FC van Wyk.
He said Parker, 65, was allegedly kidnapped by five unknown males around 09:10 at his business in Fairway Close on Monday.
A double cab light delivery vehicle had followed Parker as he was driving into the basement.
The armed men apparently forced the security guard at the gate into the toilet cubicle, where they took his cellphone and locked him up.
"They then continued into the basement where they forced the businessman into their vehicle and drove off in an unknown direction."
