On Wednesday afternoon, the Community Learning Center was in lock-down for about 30 minutes while police investigated a man near the campus carrying what appeared to be a large gun. Humble ISD Police located the man and determined that he was carrying a Red Rider BB gun, not a real weapon. The lock-down was lifted shortly after 4 p.m.The lock-down did not involve students because the CLC programs had already dismissed for the day. It did affect Child Care classes and CLC employees. Precautions are taken immediately when there is a safety concern until authorities verify that it is safe to resume normal operations.
