Chaos unfolds at London's Olympic Park after a highly toxic chlorine gas leak

Dramatic video shows chaos unfolding at London's Olympic Park after a highly toxic chlorine gas leak.

Ambulances were called to the Aquatic Centre in Stratford, East London today (23/03) after reports of an incident.

Footage shows several ambulances and paramedics swarming the area and treating those in need.

People can be seen gathered around the area outside the building, with many sat down wrapped in tin foil blankets.

A man was visiting the centre with his son at the time and recalled the moment they began to notice “a strong sharp smell that takes your breath away”.

The pair said they alerted others as they escaped the building and awaited treatment from several ambulances which had been called to the scene.
