Police admit being baffled by a series of Sewer implosions in the Colegate area of Norwich. The latest appeared in a small alleyway by Austen College. Forensics claim it would have to have been caused by a super human force trying to escape OUT of the victorian sewers.
Water Lane, an eerie ancient path that joins Colegate is still accessible, although locals admit that they now are wary. As you can see from the police hazard tape in the photo, it is not heavily cordoned.
As for the hole, Police are now looking into it.
