本人遇到咁既問題，之前做更既公司，係我唔做之前比在筆錢我還供應商商的數，但我沒有比供應商，但供應商是我相熟的，我之後跟他們說了欠條，承諾會幾時還錢，但我真係無錢還，佢地而家話要報警，咁樣算唔算刑事，警方會唔會受理？

The answer is potential criminal and yes - the police would take the case.

While typical money disputes are usually not criminal in nature, the issue is the money provided may have been misappropriated in this case.

Specifically, it is a separate matter if the supplier wanted to borrow money to you directly. The problems in this case was your employer may not be aware of the borrowing. In addition, if you have any decision-making authority over the supplier, your potential problem may be more serious.
