A Hong Kong newspaper says authorities have detained a North Korean cargo ship suspected of safety violations, just days after U.N. sanctions were placed on Pyongyang.

The South China Morning Post reports Tuesday, the ship was detained Monday after the Marine Department found 25 faults, including 12 considered severe enough to detain the vessel.

The ship arrived in Hong Kong Sunday night from Shanghai with plans to travel to Taiwan Tuesday, with a load of scrap metal.

Hong Kong's marine director Roger Tupper, told the newspaper the vessel is the ninth North Korean ship to be inspected in Hong Kong this year, and the seventh to be detained.

It is the first ship detained since the United Nations imposed sanctions on North Korea as punishment for testing a nuclear weapon earlier this month.

The sanctions aim to stop the movement of funds, nuclear and military equipment and luxury goods to and from North Korea.

The ship's captain told Post reporters he did not know about the U.N. sanctions or his country's nuclear test.
