A man has been arrested on suspicion of murder following the stabbing of a woman in north London early on Friday.
Police were called at 2.30am by paramedics to reports of an unresponsive woman inside a residential address in Neasden Lane, Brent.
Officers found a 28-year-old woman with stab wounds and despite the efforts of medical teams she was pronounced dead at the scene shortly after.
The 43-year-old man, who knew the victim, was arrested on suspicion of murder and taken to a north London police station where he remains in custody.
Her next of kin are yet to be informed and inquiries are under way to locate them.
A post-mortem examination will be scheduled in due course.
A crime scene is in place and police are not seeking any other people in connection with the incident, one of a number in Brent overnight.
Superintendent Tim Alexander said extra officers would be present in the area over the coming days.
He said: "
"I understand the community’s concerns regarding last night’s events, but I would like to reassure the people who live and work in Brent that we remain a safe and vibrant borough that rarely sees incidents of such violence.
"One of the incidents was sadly the murder of a young woman in the prime of her life. However, I would like to confirm that we have a man in his 40s in custody and that we are not seeking anyone else in connection with this incident. I can also confirm that the victim and the suspect were known to each other and that the crime happened inside a private residential property.
"Earlier in the evening, the borough also had a shooting and a stabbing within two hours of each other. Whilst this is of concern, I’d like to reiterate that my officers are working around the clock to identify, locate and apprehend those responsible.
"The community can expect to see extra officers on the streets of Brent over the coming days and I would urge anyone who has any concerns to feel free to approach them. Anyone who would rather speak to an officer in private can do so by calling Brent police via 101 or contact your local neighbourhood policing team.
"I would encourage anyone with information about any of these incidents to call police on 101. You can also contact Crimestoppers anonymously by calling 0800 555 111 or online at crimestoppers-uk.org."
