A woman has died after being stabbed in broad daylight on a London street. The victim, thought to be aged between 40 and 50, was attacked in Bruce Grove in Tottenham at lunchtime. Unconfirmed reports suggest she was stabbed in the neck.
A 46-year-old man was arrested at the scene and taken taken to a north London police station.
Leading judges have given the go-ahead for a legal challenge over police practices linked to the shooting of a man in Tottenham whose death sparked nationwide riots.
The decision by three Court of Appeal judges in London today follows an earlier High Court ruling which prevented the mother of Mark Duggan from seeking judicial review of guidance intended to stop police officers conferring before giving statements.
Lord Justice Maurice Kay, Lord Justice Aikens and Lord Justice Lewison, ruled that there was an "arguable" case, paving the way for a full hearing at a date to be fixed.
The action brought by Pamela Duggan, whose 29-year-old son died after being shot in Tottenham, north London, in August 2011, relates to a policy adopted by the Association of Chief Police Officers.
At the High Court last June she argued that the Acpo policy did not include "appropriate measures" to reduce the risk that officers directly involved in a fatal shooting conferred with each other before producing accounts.
But at that stage Lord Justice Laws and Mr Justice Wilkie blocked her bid to seek a review, ruling that she did not have an "arguable" case.
Family members and supporters reacted with shock and anger after an inquest jury concluded at the Royal Courts of Justice that police acted lawfully when they shot Mr Duggan.
The inquest jury found Mr Duggan was lawfully killed by a police marksman despite being unarmed when he was shot.
His aunt, Carole Duggan, has said the family would fight the verdict itself through the courts.

He may be one of our most senior royals, but today one Tottenham toddler just couldn't resist grabbing Prince Charles's nose as he toured the north London borough.
More than two years after it was torn apart by riots, Prince Charles went back to Tottenham to find out how the people living and working there are getting on.
Our Senior Correspondent Ronke Phillips reports.
The Labour MP for Tottenham, David Lammy, says that Prince Charles has shown real commitment to helping the people of Tottenham.

"The Prince contacted my office the day after the riots and he asked what he could do and whether he could come.
"This has been a real commitment, a sustained commitment, I might say he's been here more than any other national leader and that includes the Prime Minister."
The visit was Prince Charles's fourth since the 2011 riots and a number of his charities and organisations are helping with the borough's regeneration and providing support to young people.
Projects include an enterprise programme, run by the Prince's Trust, which provides training and mentoring for young people wanting to start their own business.
The Prince's Foundation for Building Community has also organised community consultation workshops, on behalf of Haringey Council, to develop ideas to enhance the underused Tottenham Green.
Prince Charles was visiting Tottenham to see how the area had fared since the 2011 riots. He and the Duchess of Cornwall had visited in the immediate aftermath of the riots.
The Prince of Wales viewed the site of the Carpetright building, which had burned down destroying several homes, but which has now been rebuilt.
The dramatic pictures of the Tottenham landmark glowing red hot became a iconic image of the riots.
