Arms

Freeing the upper extremities

The reasons for holding on to the arms or hands are varied, to name just a few:

Prevent of going away
Aggressive conduct in a certain direction
Block of the arms for subsequent attacks
Prevent defense techniques
Prevent of use things (cell phone, weapons, etc.)
and other

Here is probably no
defense needed!

The unwanted adherence of the hands and arms, includes not always a highly aggressive background but it is always an invasion of privacy.
The defender should carefully assess whether here a really menacing attack is carried out or can be possibly and react accordingly proportionate.

It is the responsibility principle, to the skilled martial artist and his knowledge of human nature to interpret the situation correctly and to react accordingly. Note: Sometimes less is more!
