A customs chief and six officers at the Shau Tau Kok border crossing have been detained by authorities in Shenzhen in connection with a smuggling investigation.
The crackdown is believed to be related to increased smuggling and parallel trading activities on Chung Ying Street.
The street is under the administration of the Shatoujiao customs, and is one of the worst places for parallel trading activities.
Sha Tau Kok customs chief Wu Wenhui and the deputy secretary of the Communist Party committee, Chen Ruiquen, are currently under criminal detention.
Meanwhile, a Hong Kong man was arrested by Shenzhen customs as he tried to cross the Lowu checkpoint with four kilograms of gold hidden in his sports shoes.
Customs officers saw him walking with a heavy gait.
They found four pieces of gold, each weighing one kg and estimated to be worth one million yuan (HK$1.28 million).
A merchant in the industry said Hong Kong gold has a higher and more recognizable quality than that in the mainland. BEATRICE SIU
