shots fired at a concert in the uk

Shots fired during UK rap concert is a pretty scary headline to see in my newsreader and immediately made me think of the situation in columbus where a similar thing happened. However if you read this story, thankfully no-one was hurt as the shots were just fired into the ceiling.
However I then carried on reading and saw that it took place at the Academy in Brixton, London - a club that I went to whilst at university to see Petra perform. I remember people saying that it was a rough place but the comments were in a joking tone.
