A suspected poacher was arrested between Hout Bay and Kommetjie yesterday.
A Law Enforcement Marine Unit, which was conducting a joint operation with the Table Mountain National Park Rangers, spotted a group of divers in the water.
They went to investigate, but the group dropped their illegal catch and fled.
Law enforcement spokesperson, Wayne Dyason, said: “One suspect was eventually caught and arrested by a law enforcement officer.”
Nine units of abalone were recovered.
