Any and all personnel who have entered, have currently never come out of SCP-XXXX, it is unknown if the entrance to SCP-XXXX disappears once entered, but so far, no one who has entered has come out.
Addendum:
On / /20__ a being was found inside of SCP-XXXX, the foundation has located a second SCP (this creature shall be called SCP-XXXX-1). All witnesses of it claim it is a humanoid bull like creature, highly resembling the ancient Greek myth of the Minotaur. It is said that it stands three times the size of an average human, and is five times as strong as an average human. Due to all reports, SCP-XXXX-1 has be classed as Keter as it shows to constantly be searching for an exit to SCP-XXXX, and is to remain contained within SCP-XXXX, as this is the current only known way to safely contain SCP-XXXX-1.
All Personnel that were seen by SCP-XXXX-1, were immediately chased by SCP-XXXX-1, and didn’t stop running until it caught the personnel, and is predicted to have infinite stamina. SCP-XXXX-1 then will proceed to crack the skull around the forehead of the personnel with its hands, and will consume the body of the personnel, regardless if he or she is still alive, or dead.
All attempts at terminating SCP-XXXX-1 have ended in failure, and have shown no alteration in the physical abilities of SCP-XXXX-1. Though Scars and Bullet Holes do still remain to show on the body of SCP-XXXX-1, it has proven to do no damage.
