"Computer Fraud" means "theft of property following and directly related to the use of any computer to fraudulently cause a transfer of that property from inside the premises or banking premises to a person (other than a messenger) outside those premises or to a place outside those premises. Thus, the theft ("any act of stealing") must be accomplished through the use of a computer. This may be a computer on the premises that the perpetrator gains access to, or it may be a computer located outside the premises. The controlling factor here is that the computer was used to fraudulently cause a transfer of property from inside the premises to someone, or somewhere, outside the premises.
