Pincer movement

If more than one assailant is involved, it is usual for one of
them to deploy the victim with distracting dialogue whilst
the others move to your off side. Whilst the victim is
distracted by the questioner, his accomplices attack. This
was one of the most common attacks in the nightclub when I
worked as a doorman and is a common, though,
unbelievably, innate, ploy of gang robbery or rapes.
The reason that so many people seem to get glassed or
stabbed in the side of the face or neck, is because they are
not attacked by the person in front that they are arguing
with. Instead, they are attacked from the side by someone
who they do not see, because of their adrenal-induced tunnel
vision.
