Restraint

If you have one person in the choke/restraint and are
approached by another potential attacker, release your left
hand from the choke, grip your shirt/top with your right
hand to keep the choke 'on' and use the left hand as ' fence'
to keep the other guy at bay. All the time being very careful
not to leave the choke on too heavy or the guy will fall
unconscious.
If the other attacker persists in coming forward re-connect
the choke and turn the guy that you are choking towards his
friend/accomplice so that he is now 'fence' between you and
he. If the second attacker still persists and you think that an
attack may be imminent (some people get very upset when
you touch their mates), you may be forced to place the choke
on full and KO the person that you are restraining. When you
do so slam him onto his back, unconscious, between you and
his friend. His KO'd body will act as fence between you and
attacker number two. This will give you ample time to
escape.
