JOHOR BARU - Three Indonesian cleaners who used the cover of darkness to walk along the 1km railway line of the causeway into Malaysia were stopped in their tracks.
Alert immigration officers detained the trio as soon as they reached the Bangunan Sultan Iskandar Customs, Immigration and Quarantine Complex at 4am.
It is learnt that the women, in their 20s, had documents to prove that they had applied for work permits in Singapore.
They alleged that they were abused during their stay in the island republic.
Security sources said the women, who had injuries on their bodies, claimed they were not given proper salary or food.
They also said they did not lodge a police report in Singapore about the abuses.
The Malaysian officials, who provided food for the women, refused to allow them into the country and instead handed them back to the Singapore Immigration and Checkpoints Authority (ICA) for investigation.
A source said Malaysia turned away dozens of people daily for various immigration offences, mainly for those trying to enter the country by posing as tourists.
A Singapore Woodlands security official confirmed that Malaysia had handed over the three foreigners for trying to sneak into Malaysia.
The official refused to comment, saying that investigations were still underway.
In another case, officers from the Central Narcotics Bureau and the Immigration and Checkpoints Authority arrested a 22-year-old Malaysian after they found 2kg of cannabis strapped to his body at the Woodlands checkpoint on Saturday.
The drugs seized from the man had a street value of $66,000.
According to a joint statement, the man was arrested during a routine inspection at the arrival point at 5.10am.
Investigations are being carried out under the Misuse of Drugs Act.
Under Singapore laws, those convicted of importing more than 500gm of cannabis face the death penalty.
