How can I make an npc ignore a certain player and go to the next?

Hi, I've been messing around with npcs from roblox that chase and attack you, but i've been trying to make it so you can summon an npc that attacks people for you when you use an ability, but the thing is, it doesn't go for the player, but if the player is closest to the noob it won't attack anyone else, as it only attacks the person closest to it, which in this case is the summoner.

In my script for summoning it, I put a string value inside the noob and made it say the name of the player because the chase script is inside the noob, not the summon script.

anyways, here is the chase script inside the noob. Help would be really appreciated!

local larm = script.Parent:FindFirstChild("HumanoidRootPart")
local rarm = script.Parent:FindFirstChild("HumanoidRootPart")
local summoner = script.Parent:WaitForChild("Owner")

function findNearestTorso(pos)
	local list = game.Workspace:children()
	local torso = nil
	local dist = 10000
	local temp = nil
	local human = nil
	local temp2 = nil
	for x = 1, #list do
		temp2 = list[x]
		if (temp2.className == "Model") and (temp2 ~= script.Parent) then
			temp = temp2:findFirstChild("HumanoidRootPart")
			human = temp2:findFirstChild("Humanoid")
			if (temp ~= nil) and (human ~= nil) and (human.Health > 0) then
				if (temp.Position - pos).magnitude < dist then
					torso = temp
					dist = (temp.Position - pos).magnitude
				end
			end
		end
	end
	return torso
end




while true do
	wait(1)
	local target = findNearestTorso(script.Parent.HumanoidRootPart.Position)
	if target ~= nil and target.Parent.Name == summoner.Value then
		print("Target not found")	
	elseif target ~= nil and target.Parent.Name ~= summoner.Value then
		print("Target Found")
		script.Parent.Humanoid:MoveTo(target.Position, target)
	end

end

if (temp2.className == "Model") and (temp2 ~= script.Parent) and temp2 ~= summoner.Value then
