"Just saw someone get stabbed right in front of me at garage nation.
"I’ve never seen anything like it. Why do people do this? It was honestly the scariest thing I’ve ever witnessed.
"He got cut so deep I could see like the layers of his skin it was so bad."
Garage artist H.G L-I-N-K-S tweeted: "Morons with knifes killing each other and when you stab each other you stab and kill our garage scene. Let me tell you carry a blade and you have nothing to do with what real garage music is."
A spokesperson for the Met Police said: "Officers from the East Area Command Unit are investigating. At this stage, it is believed that all four men were injured in a single incident."
