The six businesses comprised sundry shops and a barber shop.
The council has identified 150 business premises that are suspected to be operated by foreign workers.
MPKj enforcement director Shariman Mohd Nor said officers had carried out investigations on these premises based on tip-offs and found that most were being run without valid licences.
“Since the movement control order (MCO) was implemented, we have sealed 98 premises for various offences.
“Of these, more than 80% were being run entirely by foreign workers without permits and documents,” he said during the operation in Hulu Langat yesterday.
Shariman added that enforcement would continue and the local authority was serious in tackling the issue of illegal businesses, especially those being managed by foreigners.
“We will also cooperate with other agencies like Immigration Department that can take action against those working illegally.
“Most times, we find that although they are in the country with proper documents, they do not have valid work permits.
“For example, their permit allows them to work in the agricultural sector but they are working in sundry shops or at food stalls,” Shariman explained.
He added that for now, MPKj would focus on carrying out enforcement against retail businesses and then move on to food, furniture and industrial premises.
During the operation, the six premises along Jalan Hulu Langat, near Kampung Melaka, were found to be run by foreigners and without valid business licences.
A compound of not more than RM1,000 was also issued for those operating illegally.
Several items were confiscated from the premises including gas tanks, freezers and bottled drinks.
“This is meant to serve as a message to the public that we will not tolerate those that do not follow the rules.
“The public must also inform us of any wrongdoing,” he said.
Last month, the Selangor government said foreigners would no longer be allowed to apply for hawking licences in the state.
State entrepreneur development committee chairman Rodziah Ismail said Selangor passed the legislation prohibiting foreigners from owning business licences, running temporary businesses or being employed by such businesses.
She added that the changes were made given the weaknesses and lack of clarity in the current system of issuing business licences for hawkers.
Rodziah said there were three conditions that needed to be met when one applied for a business licence from local authorities in Selangor.
“The licence must be issued to a Malaysian citizen, those named as nominees cannot exceed a time frame of three months, and workers employed must be Malaysians and registered with the authorities,” she said.
