Making NPC's not arrestable

I have an many NPC’s on my server for various things. I’ve just noticed that you can arrest them, this is a huge problem, is there a code that I could add to them to make them unarrestable?

This is DarkRP, I assume, open your config file and find npcarrest or something, and set it to false.

Yes, as said above, Line 102 of Config.Lua


-- npcarrest - Enable/disable arresting npc's
GM.Config.npcarrest 					= true
