Laravel 4 Route并重定向不工作2级路径

I'm currently trying to implement redirects using

Route::get('people/foo', function() {
    return Redirect::to('people', 301);
});

That won't work, will give a 404, but doing 'people/foo/bar' will redirect correctly.

Route::get('people/foo/bar', function() {
     return Redirect::to('people', 301);
});

What could be the cause of this, I've tried different variants.

Do you have another route that's intercepting requests to people/{whatever} like:

Route::get('people/{id}', 'PeopleController@show');

or

Route::resource('people', 'PeopleController');

If so, then you'll need to place this specific route before that one.
