KUALA LUMPUR: Bukit Aman says efforts to track down Chong Sum Yee are underway by Thai police.
Police Force secretary Deputy Comm Datuk Noorsiah Mohd Saaduddin said a report was lodged by the woman's mother last Friday (June 2).
"Thailand police are in the midst of tracking down the woman with the help of Interpol and our police force.
"Myanmar police and other agencies in Thailand are also cooperating in the search efforts," she said in a statement Wednesday (June 7).
Chong, 22, had flown to Chiang Mai on May 29 and travelled about 250km to the northernmost district of Mae Sai in Chiang Rai province in northern Thailand.
The place is close to the neighboring town of Tachilek in Myanmar, where incidents of human trafficking had been reported previously.
Chong remained in touch with her family while in Thailand, and was last heard at about 10.30am (local time) on June 1.
According to CCTV footage obtained from a hotel, a young woman who bore a resemblance to Chong was captured sitting in the hotel lobby. Subsequently, another woman arrived and both left the hotel on a motorcycle.
From the CCTV footage, there was no evidence of coercion or force being used.
On Friday, Chong's mother, Chee Choy Wen, took to Facebook to express her concern after unsuccessful attempts to contact her daughter. Consequently, a police report was filed on June 2.
