Commuters were left terrified when sick yobs sprayed a mystery liquid on them in an apparent prank 'acid attack' video filmed on the London Tube network.
Video filmed on the Victoria line and uploaded to social media shows two youths squirt the unknown liquid from what looked like Lucozade bottles.
Those targeted included a male commuter who was squirted through a closing train door, a woman looking at her smartphone - also squirted as the doors closed - and a man on an escalator with luggage.
One message on the video read: "Don't sleep on the job".
They also wrote: "No-one catch the Victoria line".
The youths can be heard laughing after each of the attacks in the video.
