A one-month old male Rohingya infant was among 45 undocumented foreigners held in an operation at two construction sites by the Immigration Department in Taiping, Perak last night.

Immigration director-general Mustafar Ali said 159 foreigners were screened in the operation, which began around 10.30pm and ended at 2.30am.

He said the detained foreigners, comprising 39 men and six women, were Myanmar, Indonesian and Bangladeshi nationals.

"Some of them had escaped from their employers to work at the construction sites,” he told reporters after the operation carried out at Taman Aor Jaya and Jalan Taman Lake View here.

He said the foreigners were brought to the Immigration office prior to being sent to the department’s detention depot in Langkap.
