Problems with Team Door. When run it gives a not part of error. Can I have some help?

I have a door whereas when a Player on the team Police touches the door, it will open. I have the opening script done, but for the game to check if the Player is on the Police team is failing. I have some code snippets for it

First, the Variables:

--Vaiables
local Sensor = script.Parent.Sensor
local Door = script.Parent["Prison Side Door 1"]
local Window = script.Parent.Window
local PlayerV = game.Workspace:FindFirstChild("Head")
local Light = script.Parent.Light
local Sensor = script.Parent.Sensor
local db = true
local Police = game:GetService("Teams"):FindFirstChild("Police")

Then the function that runs when the Sensor is touched:

--Function for everything


local function Everything(part)
    local plr = game.Players:GetPlayerFromCharacter(part.Parent)
    local hum = part.Parent:FindFirstChild("Humanoid")
    print('found humanoid')
    if hum then
        local Player = part.Parent
        local Character = workspace:WaitForChild(Player.Name)
        local music = Instance.new("Sound",Character)
        music.SoundId = "rbxassetid://993959716"
        music.Name = "AMusic"
        if db and Player.Team == Police then
            db = false
            music:Play()
            Light.Color = Color3.fromRGB(0,255,0)
            Door.Position = Vector3.new(-155.7, 105.225, -332.925)
            Window.Position = Vector3.new(-155.65, 106.626, -332.925)
            wait(4)
            Door.Position = Vector3.new(-156.6, 105.225, -327.925)
            Window.Position = Vector3.new(-156.6, 106.626, -327.925)
            Light.Color = Color3.fromRGB(255,0,0)
            db = true
        else
            warn("This Person is not a Police Team Person")
        end
    end
end

Finally, the connect function:

Sensor.Touched:Connect(Everything)

The Error it gives is on line 26 and it is:

17:33:39.710 - Team is not a valid member of Model

Any Ideas on how to fix this?
