JOHOR BARU, April 9 — The police will begin their investigation into the incident where four foreign divers went missing in waters off Pulau Tokong Sanggol, Mersing after the three victims who were found safe.

Johor police chief Datuk Kamarul Zaman Mamat said the investigation will cover various aspects, including the qualifications of Norwegian dive instructor, Kristine Grodem and whether negligence occurred during the dive.

"Yes, we will investigate various aspects, including if there was negligence in the way the training was conducted, and whether the training session had complied with regulations or existing standard operating procedures.

"For now, the rescued victims are still traumatised and they need time to recover, as soon as they are stable we will record their statements for further investigation,” he told reporters after a breaking of fast event for Op Tambak police officers and personnel at Angsana Johor Baru Mall here today.
