That video is really scary to look at - thank God those people heard her cries and threw the life rings out to her......otherwise ?
Great work by the rescuers too and timely - and, I have to say, the guy filming it with his concerned commentary....and finding her mobile phone literally inches from the wall edge !
The Mersey should never be under estimated - I always remember as a small kid getting stuck in the mud near the Cazzy and my older brother screaming at me, as the tide was coming in......and it moved extremely fast. He managed to grab me and pull me out before the both us were swallowed up ! Taught me to hugely respect the river after that.
