Abandoned High Royds Hospital Escape

Abandoned High Royds Hospital, a former psychiatric hospital located within in the City of Leeds at the south of the village of Menston in West Yorkshire, England. It was closed in 2003 since then the site has been undergoing development. One day I was going to that Abandoned High Royds Hospital with my family. I exclaimed by its design and went inside to see the interior view. Suddenly the main door has locked by some unknown person. So please let me escape out from that Abandoned High Royds Hospital using your tactics. Have fun.
