Special Containment Procedures: 

SCP-173 is to be contained in a 10x10x10 concrete box. Any testing for SCP-173 has to be conducted by at least 1 scientist, 2 armed personnel and 3 Class-D Subjects.  In the events of a containment breach, personnel with a SCP-173 re-containment box are to box up SCP-173 as soon as possible, while personnel in contact with SCP-173 should keep an eye open to avoid getting their neck snapped.

Description:
SCP-173 is a statue composed of Concrete, Rebar and Krylon spray-paint. SCP-173 is a sort-of statue that will only move if the line of sight does not exist or is broken for any time. SCP-173 moves at rapid speeds and will snap the neck of the closest victim of SCP-173. SCP-173 cannot move in direct eye or camera contact. SCP-173 is an extremely hostile anomaly, moving from target to target if not observed. If observed, the object cannot move unless eye contact is broken at any time, may it be a blink or a sneeze. Scraping inside the SCP chamber is normal, but any changes in behavior should be reported and responded to immediately.
