I am not sure about 'criminal intrusion' in the memo sent by a student:
'In order to prevent criminal intrusion do not leave your office unattended. When you leave your office, you should lock it.'
Maybe we should say 'in order to prevent office break-ins' or 'in order to prevent stealing things from offices'?
Could you share your ideas please?
Thank you in advance.
Please lock your office doors in order to deter theft.
