Australian-born former tennis Grand Slam champion Bob Hewitt was found guilty on Monday in South Africa of raping and assaulting young girls whom he was coaching in the early 1980s. Hewitt, 75, had pleaded not guilty to the two charges of rape and one of indecent assault, which were brought against him by three women in 2013. Judge Bert Bam at the South Gauteng High Court outside Johannesburg described the evidence against Hewitt as “overwhelming”, the SAPA news agency reported. “Time didn’t erase the crimes. A guilty person should not go unpunished,” Bam said.
