A bag defining an interior space and an opening. The bag includes a closing member which is connected to the body. The closing member is movable between a first position, which allows access to the interior space of the body through the opening, and a second position which prevents access to the interior space of the body through the opening. The bag includes a handle and a lockable member connected to the body. The handle includes at least one removable end. The lockable member is adapted to secure and lock the closing member and the removable end of the handle to the body when the closing member is moved to the second position to protect the bag and the items contained in the bag from being taken.
