Accessories to prevent iPad Pro and iPhone from being robbed on subway

[hajime]

Hi, I plan to use an iPad on subway but I heard that there have been robbing cases. Basically some bad people waited for the door to open, then suddenly and quickly grabbed the laptop/iPad/iPhone from users and escaped quickly. What accessories can be used to prevent this from happening?

Hide it in a bag.

Buy an iPad case with a Kensington lock, and tie it around your waist.

Or with a Strap wearing it around your neck.
