Conduit used as a support

In a recent inspection of an electrical contractor's project I spotted several conduits with (1) #6 insulated wire (green) tyrapped to the outside of the raceway. These wires originate at several different area ground busses. These bonding jumpers terminate at several instrument junction boxes (120VAC & 4-20 ma).
I am aware wires, cables, other conduits, etc. can not use a conduit system for support by securing to the outside. A separate conduit or cable tray should be installed for the equipment bonding jumpers.
I was asked, "show me in the NEC that I can't do this".
Please help with the location in the NEC of this issue.
 
Re: Conduit used as a support

In general 300.11(B) prohibits using raceways as supports with some exceptions.

If this is an equipment bonding jumper 250.102(E) may allow this installation
