How can I stop team from stealing their own teammate ball?

There is a basketball for a roblox basketball game, the steal script works fine, but the problem is my own teammate is stealing the ball. How can I stop my teammate from stealing the ball but allow the enemy team to steal it? Location: http://prntscr.com/jnq732

function onTouched(hit)
if hit.Parent:FindFirstChild("Humanoid") ~= nil then
script.Parent.Parent=workspace
wait()
script.Parent.Parent=hit.Parent
script.Disabled = true
wait(2.5)
script.Disabled = false
end
end
script.Parent.Handle.touched:connect(onTouched)

To make your teammate not steal the ball, you could store an array or a folder that includes your teammates' names (i.e local array = {"Player1","Player2"})

I don't know the value of HandValue. I am guessing it is an object value that says which team or player has the ball(please correct me if I my statement is incorrect). So if it is, you could use that to insert the team in the team array.

Here is how your code would look. By the way, please indent when making code, it makes your code look neat.

local team = {} -- this is where your teammates' names are stored
function onTouched(hit)
	if hit.Parent:FindFirstChild("Humanoid") then -- you don't have to have "~= nil" in here
		script.Parent.Parent= workspace
		wait()
		script.Parent.Parent=hit.Parent
		script.Disabled = true
		wait(2.5)
		script.Disabled = false
	end
end
script.Parent.Handle.Touched:Connect(onTouched) -- connect is deprecated. Use Connect. Roblox recommends developers to use syntaxes that are not deprecated

Hopefully this gave you an idea on how to make your teammates not steal the ball if your team has it.
