Humpback spotted in the River Thames

This is the staggering moment a huge humpback whale surfaced -- in the River Thames.

Shaun O'Riordan, 52, was at work when the massive mammal came to the surface for air this morning (07/10).

The animal appeared at around 7.30am and headed into the capital for around 40 minutes, before passing back through Dagenham, towards the sea.

Automotive worker Shaun said: "I've seen a few seals and even some dolphins but I've never seen a whale in the Thames."

This video was captured 6th October 2019.
