The Ghana Immigration Service has mounted surveillance on its officials after it emerged one of its own was involved in aiding the illegal entry of some Chinese nationals into the country.Public Relations Officer of the Service Francis Palmdeti who disclosed this to Joy News said the surveillance is one of the measures the Service is putting in place to flush out miscreants who dent the image of the service.“Instructions have gone to all our various controls around the country to step up border patrol activity to ensure that such individuals do not cross unapproved routes,” he said.It follows the arrest of a junior officer of the service stationed at the Ghana-Togo border Moses Alale. He was arrested upon a tip off two weeks ago but has since jumped bail.Alale has aided in the entry of 15 Chinese nationals into the country without the required documents.Francis Palmdeti said it was “unfortunate” that upon all the trainings given their officers to be “very professional”, an officer who “should know better” would engage in such an act.
