The three accused had set up make-shift stalls on a pavement in the industrial estate of Tuas, earning four Singaporean dollars per haircut compared to the average hair cut cost of 10 Singaporean dollars in a local barber shop.
Officers from both the Manpower Ministry and the National Environment Agency raided the area and arrested the three on Sunday, while others at the scene fled.
The ministry was questioning them for violating their work permit under the Employment of Foreign Manpower Act. An offender in such a case can face a fine of up to 20,000 Singaporean dollars and two years in jail.
The Environment Agency was also investigating the three for offering barber services at an ‘inappropriate site’.
Under the Environmental Public Health regulations, it is an offence for an individual to act as a barber in areas such as roads, footways and back lanes.
The three accused said they were moonlighting to earn extra money for themselves or their families.
