Singer Asake, who also goes by the name of Mr Money, had been preparing to hit the stage at the O2 Academy in Brixton on Thursday when the concert descended into chaos.
The internationally successful musician has been performing to fans on his first UK tour, previously performing in Birmingham and Manchester days before disaster struck in London.
On Thursday night, Asake, 27, had been set to perform to a sold-out crowd at the South London venue but the show was brought to a halt.
