A town councillor has come up with a theory about the mysterious tunnel recently found at Tenby's Gas Lane.

Clr. Trevor Hallett believes the tunnel, discovered during excavation works for the new Glen Pharmacy, was an 'exploration shaft for iron ore'.

In response to a letter from Dr. Alun Morgan, of North Cliffe, which came before a meeting of the council on Wednesday, Clr. Hallett explained that work on the pharmacy was continuing, but the entrance to the tunnel had been secured and a doorway made for access to be maintained.
