Symfony \ Component \ Debug \ Exception \ FatalThrowableError (E_ERROR) Class 'App\Http\Controllers\Redirect' Not Found

Suppose you have written Redirect code as follows:

    public function destroy($id)
    {
     $user = User::find($id);
     $user->delete();
     return Redirect::route('index');
    }

Then when you are debugging it's showing the error as:

Symfony \ Component \ Debug \ Exception \ FatalThrowableError (E_ERROR) Class 'App\Http\Controllers\Redirect' not found

The solution is, you have to import the following  class in controller. 

 use Illuminate\Support\Facades\Redirect;
