A failed attempt to cut open an ATM at an Agrobank branch in Taman Sungai Yu, Sungai Buloh early this morning, left the robbers empty-handed.
Kuala Selangor OCPD Supt Mohd Taib Ahmad said the attempt was detected by a bank customer who wanted to withdraw cash at 7.48 am.
Police found two burnt holes indicating that an oxy-acetylene flame was used on the metal door.
There was also an attempt to prise open the door.
The thieves had also stuck black tape over the CCTV cameras, to avoid detection.
Police have recorded the statements of several bank employees to facilitate investigations.
