Within seconds he approaches a man who can be seen scrolling on his phone and blasts him in the face with a fireball.

The terrified victim ducks before running for cover and ripping off his coat.

The nut pursues him and fires a second inferno into his back before turning on another man.

CCTV footage shows the second victim's head get doused in flames as witnesses jump for cover.
