A man has been stabbed to death in Newham in the seventh fatal knife attack in London in seven days.
The victim, believed to be 29, was found injured following reports of a fight in Silvertown.
It was the 146th murder of 2019 in London, making the year the bloodiest since 2008.
Police were called by paramedics shortly after 2am on Saturday to reports of people fighting in Hanameel Street.
The man, who had been stabbed, was pronounced dead at the scene and his next of kin have been informed.
One man has been arrested and remains in custody, as the investigation continues.
The east London stabbing was the latest in a string of knife murders across the capital in the last week, including three in little over four hours on Thursday.
At 7.15pm a man in his twenties died of stab wounds in Walthamstow. A 29-year-old man has been arrested on suspicion of murder.
Less than an hour later, police were called to a fight in Barnet but found no victims or suspects at the scene.
At 8.30pm, they were called to a nearby bypass where a man in his thirties was found with fatal stab wounds inside a car.
Three hours later, police were called to a stabbing inside a home in Hounslow.
Three suspects are believed to have forced their way inside the property and murdered 35-year-old Ebrima Cham, known as Brim, in a targeted attack. One man has been arrested.
Albert Amofa, 33, died in hospital after suffering a stab wound in his leg in Croydon on Sunday.
Police said he “was simply returning home to be with his family” when he was attacked.
On 14 December, 49-year-old Viorel Stefan was stabbed to death at a property in Dagenham shortly after 10pm. Vasile Firanda, 59, has been charged with murder.
On the same day Dmytro Balaban, 28, was fatally stabbed in Brent. Volodymyr Holovatskyi, 23, has been charged with murder.
The Metropolitan Police is part of a London-wide Violence Reduction Unit, and has set up a squad attempting to use social media posts to predict outbreaks of violence and gang crime.
Earlier this year, commissioner Cressida Dick claimed violent crime was falling following an increase in the use of stop and search.
She previously said there was “some link” between the loss of more than 20,000 police officers since 2010 and rising violence.
As prime minister, Theresa May claimed there was “no direct correlation”, but Boris Johnson has vowed to recruit 20,000 new police officers in the next three years and increase stop and search powers further.
