Hong Kong Police have arrested four persons over suspicion of entering the city illegally on Monday, media reports said.

Four other suspected illegal immigrants who accompanied the Pakistani passport holders on the double-decker bus to Shau Kei Wan were being hunted, the force was quoted as saying by South China Morning Post.

Shortly before 8.30am, police received multiple calls from passers-by who spotted on Cape D’Aguilar Road in Shek O a group of eight non-Chinese men thought to have entered the city illegally, the newspaper reported.

Police searched and carried a roadblock in the area after the Pakistani nationals escaped the spot.

About half an hour later, a bus driver made a report to police about eight suspected illegal immigrants jumping into the vehicle on Cape D’ Aguilar Road in Shek O. They got off at Shau Kei Wan bus terminal on Aldrich Street, the newspaper reported.

The four people were apprehended on Po Man Street.

On Saturday, four non-Chinese men were arrested on Peaked Hill, southwest of Lantau Island, after a fisherman alerted the authorities when he spotted the group in distress, the newspaper reported.
