A young woman has died after “becoming ill” at Wireless on Sunday – the second of this year’s festivalgoers to die.

The 20-year-old told was at the Finsbury Park event headlined by Drake when she told staff she felt ill and asked for medical treatment.

She was taken to hospital, where she died on Monday.

Scotland Yard said an investigation had been launched into what led to her death and enquiries are ongoing.

A 16-year-old boy also died on Sunday after suffering a suspected asthma attack while leaving at about 9.40pm.

He got the attention of police in Seven Sisters Road, who gave emergency first aid before medics arrived, but died in hospital at 12.30am.
