High Current/Voltage will pull people
High voltage leads to high current, so you can't separate them and AC and DC are just as deadly, whatever Edison and Tesla used to claim.

Current flow causes muscles to contract - that's how they work. Sometimes you get lucky and the path the current takes causes the right muscles to contract to throw you away from the source of the electricity, but usually the layout of the human body means that the reverse happens and you get more tightly attached to it, most often by closing your fingers around a wire.
