It is recently noted that insecurity at workplace is shaping up as a major concern in the company. There were three reported cases from members of the staff whose money had been stolen. Staff are, therefore, required to observe these regulations in order to practice and foster a risk-free working environment:
+ Valuable items must be kept carefully (i.e. with the owners or inside a locked drawer...)
+ Any suspicion arising from any individuals must be informed promptly to the security team.
+ Any found guilty acts will be treated with serious punishment which varied from dismissal to legal actions taken.

Please correct if there is any grammatical mistake or odd expression. Make them more English-like (wrtiten by a native English writer)

Thanks in advance.
