Families and communities in London have been left in shock after a series of stabbings during the heatwave.
While millions of people have been enjoying days of record hot weather, the capital has also been hit by a number of “horrific” incidents of violence.
Police launched a murder appeal after a teenage boy was stabbed during a street fight in Hackney.
The victim was found by officers in Poplar Close after reports of machete-wielding thugs in Towpath Walk around 7.15pm on Monday.
The violence is believed to have started at a nearby house party.

The following day, a man in his 20s was stabbed to death in north-west London.
Police were called shortly before 8pm on Tuesday to a report of a heated row on Ashmore Road in Kilburn.
Ambulance paramedics gave emergency treatment to the man but he was pronounced dead at the scene.
Florence Eshalomi, co-chair of the All-party Parliamentary Group of London MPs, told the Standard: “First and foremost thoughts go out to all the families and the wider community affected.
“When people are enjoying the weather, unfortunately there will be a very small minority intent on causing harm and violence.”
The MP for Vauxhall and Camberwell Green added: “It is important for us to continue to work with local councils, the police and the Mayor’s office but most importantly with the community.

“This has to be communities working together to promote zero tolerance of violence on London’s streets.”
But shadow home secretary Chris Philp, MP for Croydon South, pointed the finger of blame at the Government and London Mayor.
"Labour and Sadiq Khan have lost control of our streets in recent days as feral youths, often armed with knives, are running amok,” he stressed.
“The violence we have seen is completely unacceptable.”
Lib Peck, director of the Mayor of London's Violence Reduction Unit, said: “My thoughts and prayers are with the family and friends of all those impacted by these truly horrific incidents.
“We are committed to doing everything possible to preventing knife crime and violence from happening in the first place.”
She highlighted a 50 per cent fall in hospital admissions of young people for knife assault in the last seven years.
“But it's clear there is more to do to drive violence down in London and that must involve a concerted focus on both policing and prevention, including funding positive opportunities for young Londoners to keep them safe and supported to thrive,” she added.
The number of violent offences tends to rise during periods of high temperatures as people stay out later, possibly drink more alcohol, and behave in ways that they might not on cooler days.
This trend has been evident from a number of events including most starkly the London riots of 2011.
At the start of the Bank Holiday weekend of unprecedented hot weather, a 17-year-old boy was stabbed after a mass “unauthorised gathering” of teenagers in Clapham.
The teenager was rushed to hospital where his injuries were found to be non-life-threatening.
Fighting had broken out at the alleged music event on Friday on Clapham Common.
Police officers, who responded in dozens of vehicles to the outbreak of violence, made nine arrests and dispersed a large group of people.
On the same day, five men were assaulted and stabbed in Horn Lane, Acton, west London.
Four of the men, aged 20, 22, 42 and 47, were taken to hospital.
Their injuries were not believed to be life-threatening or life-changing.
Meanwhile, a man has been charged after an A&E doctor was stabbed while on duty at Hillingdon Hospital, west London, in the early hours of Tuesday.
The doctor, aged in his 50s, was treated at his own hospital for stab wounds which were not believed to be life-threatening.
The day before, as temperatures spiralled to a record high in London hitting 34.8C, Hampstead Heath’s Parliament Hill Lido was closed following a fight at the beauty spot.
