A tobacco retail outlet at Bedok North Avenue 2 has had its licence revoked for selling cigarettes to underaged youths.
The shop, Lam Chang, will no longer be allowed to sell tobacco products from May 1.
Health Sciences Authority (HSA) inspectors caught an employee in the shop selling cigarettes to two students in school uniform - aged 13 and 15 - within a span of five minutes on Wednesday.
Apart from having its licence revoked, the seller has been convicted in court and fined $2,000.
Two other shops were also caught selling tobacco products to underaged youths at Hougang Street 52 and Bukit Batok East Avenue 4.
Fair Price Underground Super Store and Nirmala Provision both had their licences suspended, with the sellers convicted in court and fined for their respective offences.
Under the Tobacco (Control of Advertisements and Sale) Act, anyone caught selling tobacco products to persons below the age of 18 can be fined up to $5,000 for the first offence and up to $10,000 for the second or subsequent offence.
Their tobacco retail licence will also be suspended for 6 months for the first offence and revoked for the second offence.
Those caught selling tobacco products to youths under 18 in school uniform or those below 12 will get their licences revoked, even at the first offence.
