Johor Police have arrested eight individuals including three workers of a private clinic here on alleged involvement in the sale and purchase of fake Covid-19 vaccination certificates.

Newly appointed Johor Police chief Kamarul Zaman Mamat said all the suspects, five of whom were buyers aged between 24 and 42, were nabbed last Monday and Tuesday following a report lodged by the owner of the clinic on Sunday.

He said the police were now in the midst of tracking down 30 other individuals who had bought the digital certificate without getting the jab, including a 44-year-old man believed to be the mastermind of the activity.
