A woman stabbed to death in the rush hour yesterday morning has been named by police as 45-year-old Alison Morrison.
Mrs Morrison is understood to have been on her way to work when she was set upon and knifed near her home in Harrow, north west London.
According to reports, her neighbour - satellite TV engineer Trevor Gibbon, 48, was arrested by police, and a large bloody kitchen knife was found nearby.
Neighbours reportedly claimed the pair had been locked in a bitter dispute over a shared driveway between their end-of-terrace houses.
Mrs Morrison is also said to have installed a bright security light which upset her neighbour, while Mr Gibbon had erected CCTV cameras on his home which caused animosity between the pair.
Neighbours heard piercing screams and police were called to the attack in Alexandra Avenue at 7.47am yesterday.
Mrs Morrison was taken to St Mary's Hospital in Paddington, west London, where she died from her injuries.
A post-mortem examination will be held later today and a police family liaison officer is supporting Mrs Morrison's family.
Scotland Yard said: "A man, aged 48, was arrested in Lincolnshire on suspicion of murder and taken to a north London police station where he remains in custody.
"Inquiries into the circumstances surrounding the incident are ongoing."
Detective Chief Inspector Matt Bonner, of the homicide and major crime command (HMCC) - who is leading the investigation, said: "The thoughts of the Metropolitan Police Service go out to Allison's family at this terrible time.
"Alexandra Avenue is a busy thoroughfare and I am sure that there will have been people who may have witnessed all or some of the incident who are yet to come forward.
"I would appeal to anyone who was in the area between 7.30 and 7.50 on the morning of Thursday to contact police."
