He recalled how he arrested Gift after he gave his real name to the victims he raped and robbed.
"That was not the only thing that allowed us to narrow down our search for the rapist.
"Some of the victims said Gift would hoot and greet other taxi drivers along his routes after he kidnapped them.
"This indicated Gift was a taxi driver and was known in the taxi industry," Mokoena said.
He said he organised meetings with taxi associations in areas where the incidents appeared prevalent.
"It was not easy because all the victims were abducted and raped in a Toyota Quantum - there are hundreds of them on the road. But we eventually found him after he and his friends abducted a woman in Westdene on October 12 2017," he added.
"He didn't know there was a CCTV camera where the abduction occurred," Mokoena said.
On the day of the arrest, Gift had remained quiet when Mokoena and his colleagues knocked on his door.
He is set to be sentenced again tomorrow in the Roodepoort Regional Court for different set of charges where he was found guilty of rape and robbery with aggravating circumstances.
Mokoena said Gift's life would have turned out differently if he had a father figure.
"He got involved in crime at a very young age".
Mokoena, who wanted to be lawyer while growing up, said he was pleased with his career path because it has allowed him to serve people.
