Royal Malaysian Navy (RMN) chief Admiral Tan Sri Abdul Aziz Jaafar has confirmed that authorities have reportedly lost all communication with the RMN gunboat CB 204 while en route to Gugusan Semarang Peninjau on Sabah waters.

There are seven officers on the gunboat, he said in his Twitter.

The gunboat’s last known position was 20 nautical miles northeast Pulau Mengalum around 1.05pm Sunday.

RMN ship KD Paus was instructed to escort CB 204 and had departed from the Kota Kinabalu navy base (PTKK) at 5am.

At 10.30am, the operating room of the Wilayah Laut II headquarters (MWL 2) had received a call from KD Paus informing the ship and gunboat would be turning back to the PTKK due to bad weather.

However, at 1.05pm, KD Paus failed to establish communication with the gunboat. The ship then launched a search between Pulau Mengalum and Pulau Gaya but was unsuccessful.

Ships from the Malaysian Maritime Enforcement Agency (MMEA) have been instructed to join the search and rescue (SAR) mission.

KD Lekiu and KD Serang departed PTKK to Pulau Mengalum at 5.30pm to join the SAR mission.
