Police investigating an abalone poaching operation in Hawston, near Hermanus, detained three people for questioning on Monday in connection with three separate murders in Hermanus in 2016, 2018 and earlier this year.
Police also seized more than R600,000 in cash and diving equipment.
Ten properties were searched and more than 30 people were questioned.
“It is believed that the diving equipment is used for poaching purposes and that the cash was raised through the proceeds of crime,” said police spokesperson Andre Traut.
“Once charged, the three suspects will make court appearances in Hermanus,” Traut said.
