KUALA KEDAH (THE STAR/ASIA NEWS NETWORK) - Mr Muhammad Aiman Shafiz Marzuki, 20, was doing his six-month practical training aboard MT Orkim Harmony as a crew member when the tanker went missing last Thursday.

The practical training is necessary for him to fulfil the requirements to graduate with a Diploma in Shipping Engineering from Ungku Omar Polytechnic, Ipoh.

His mother Habibah Baharum, 43, said she last saw Mr Muhammad Aiman Shafiz at the Shabab Perdana bus station in Alor Setar on May 27 when seeing him off to Kuala Lumpur.

"I don't ask for much. I just want him to be found safe. That is our family's wish," she said.

Ms Habibah told the media that the family held prayers at their house in Taman Seri Marina Phase Two here on Monday, and at a nearby mosque, to pray for Mr Muhammad Aiman Shafiz's safe return.

She said the owner of MT Orkim contacted her husband a few days ago to notify them of the tanker's disappearance.

The company said they had lost contact with the tanker as it went undetected on the radar.

Ms Habibah said her son had pursued the diploma course because he wanted to be part of the industry.

According to her, Mr Muhammad Aiman Shafiz had been producing excellent results throughout his studies at the polytechnic.
