Samuel, my uncle and I just had to get on the floor as a gunman ran through the pub we're in.
It happened at the George pub in Borough - a black man with a gun that looked like an AK47 ran through. Men started chasing him and shouting "get down he has a gun."
I have never had to get down on floor before. The whole moment was surreal and I didn't react fast enough. Samuel and my uncle hit the floor.
I called the police but they're still not here. Gunman was carrying a gun with a Sports Direct bag in tow.
Three armed police have now arrived and are pursuing suspect.
