Alexandra Palace has said the death of a concert-goer at Friday night's Bring Me The Horizon gig was due to a "tragic medical incident".
Emergency services were called to the venue at around 10pm after receiving a report of a man feeling unwell. The man, who has been named locally, is understood to have died at the scene. His cause of death is currently unclear.
"A medical incident occurred at last night’s Bring Me The Horizon concert," said the venue in a statement. "Our thoughts and condolences are with the individual's family and we would like to express our deepest sympathy to them. We hope you can appreciate we cannot provide any further comment at this time."
The venue has defended itself against criticism of its security measures on social media.
"We would like to clarify that this was a tragic medical incident and unrelated to the extensive security measures in place," it said. "However, we feel we must address inaccurate information. There were over 150 security personnel on site for the concert."
Bring Me The Horizon, who had also played the 10,400-capacity venue the previous evening, released the following statement: "Words cannot express how horrified we are feeling this evening after hearing about the death of a young man at our show last night. Our hearts and deepest condolences go out to his family and loved ones at this terrible time. We will comment further in due course."
