A Liverpool man has been uncovering hidden parts of Liverpool and its surrounding areas in a YouTube series.
George Toohey, 44, takes his followers inside hidden gems that can be found in the city, from caves, to tunnels and even a secret entrance to the cellars beneath Otterspool House.
The Liverpool man captures his explorations on his YouTube channel G2E Media, and this time has taken to another underground passage where a hidden river flows beneath the city.

The River Jordan, also known as Little Jordan or Otterspool Brook, is a tributary of the River Mersey and has been culverted for most of its lower course.
George Toohey told the ECHO : "The finding of this one stems back to when I was a child.
" At the entrance to Otterspool Park, if you look to the left, you can see where the actual river emerges from Sefton Park, and that is the last point you can see before it goes underground.
" I briefly popped in there around 2010, so when I showed my friend Eric we thought it was fascinating because it is kind of lost forever to the River Jordan."
He added: "Some of the brickwork inside, you hardly see that nowadays, some of it has been repaired because there was a collapse on it, but I think they have done a good job of it.
"There is another part to it, which I need to get round to exploring and filming, I have never seen this part of it, it is just a case of 'when' at the moment to be honest."
In the video George can be seen talking to his friend Eric deep in the tunnels as the pair discover eels within the water.

In the video George said: "It [the tunnel] bends around by the cafe, into the woods, then it comes into a chamber, and then it spits out into the Mersey."
The hidden river is fed by two brooks, the upper brook stems from around Wavertree Technology Park, flowing underneath the Brookhouse Pub, which George said he believes is "where that got its name from", it then heads down under the student residences near Greenbank park, then into the Fairy Glen in Sefton Park.
George said: "The lower brook I believe is from Smithdown Cemetery and then into the grotto in Sefton Park, there’s a waterfall in there that was fed by the River Jordan, and both of these meet up around the Iron Bridge.
"Once they hit the Boating Lake, there is a u-bend and it drains out then into Otterspool."

He added: "Every time I go around that way I am always looking for little things to explore, it absolutely fascinates me."
George told the ECHO that being able to discover and document these places for people who may never have seen them is what he loves most of all.
He said: "To discover things like this, whether new or not, but there is no photographic or video evidence of it, it is great to be able to take it to show everyone what is hidden away.
"We have a very extensive list of things that we believe have never been seen around Liverpool, so it is just finding the time to do it at the moment."
