A man stabbed a woman to death and left a second woman in a critical condition after an attack in Wolverhampton, police said.

Armed officers and a dog unit rushed to a block of flats in Leasowes Drive, in the Merry Hill area of the city, also known as Warstones, where it is believed the man attacked two women before stabbing himself.

Officers said they used stun grenades as they stormed the flat in a bid to distract and detain the attacker.

A woman believed to be in her 30s died at the scene and a man, also believed to be in his 30s, was pronounced dead a short time later from what are thought to be self-inflicted wounds.

Another woman, believed to be in her 50s, was taken to hospital with critical stomach wounds.

A police officer was also treated for minor injuries on the scene by ambulance staff but was quickly discharged at around 9.45am.

An ambulance spokesman said the man and woman suffered "very serious stab wounds" and said the second woman was in Queen Elizabeth Hospital in Birmingham with "potentially life-threatening stab wounds".

"Sadly, despite best efforts by ambulance staff, it was not possible to save either of them and they confirmed them dead at the scene," said the spokesman.
