They returned to Sandakan, Sabah on Wednesday and later they were flown to Kota Kinabalu to facilitate investigations. They also met their family members who came all the way from Sarawak to meet them.

However, Sabah Police Commissioner Abdul Rashid Harun refused to comment on when the four will be allowed to go back to Sibu. But he said that they were still in Kota Kinabalu.

AFP reported that in a simple text message, he said, "Let us do our job".

The four sailors were kidnapped by eight armed men in the waters of Semporna, off Pulau Ligitan while they were returning to Malaysia from Philippines.
