A murder investigation has been launched after a woman’s body was found in a flat where a "blood-covered" man allegedly jumped from a second-storey window before going on a "rampage".
Police discovered the body after they arrested the man and gained entry to the flat in Ancoats in Manchester city centre.
The woman’s death is being treated as suspicious, and a 37-year-old man is being held on suspicion of murder.
Horrified witnesses described how the man plunged from a second-storey window and landed on a car before attacking a family and others in the street.
Ben Sheridan, 28, told the Manchester Evening News that he and his parents felt a huge bang on their car’s roof and then discovered the bloodied man.
They jumped out to help him, but he started to attack them before running down the street and trying to drag a woman from her car, it was claimed.

Police officers rushed to Swan Street in Manchester city centre following reports of a man behaving "erratically" at about 7.40am.
Witnesses said the man leaped from second-floor window – smearing it with blood – and landed on the Hyundai i30, leaving its roof partially caved in and its windscreen smashed.
Ben, a web developer, was in the car with his mum Lynn and dad Peter. They had just parked up and were preparing to go to work when the man landed on the vehicle, they said.
Ben said: “He was hitting my mum in the face, my dad was trying to get him off. We are all in shock.”
His dad Peter said that the family were left "shaken" following the incident.
Peter, from Radcliffe, said: “It’s the first time I’ve ever had to fight. My wife has a huge lump on her face. We are all very shaken up.”
It was claimed the man then ran down the street, smashing the windows of at least two cars – a BMW and a Volkswagen – with his hands and assaulting people.
A man said his 34-year-old sister was in her BMW on her way to work at Salford Royal Hospital when a man "on a rampage" smashed her rear window before trying to drag her out.
The brother said: “He tried to drag her from the car, she was screaming and trying to stop him. He was smearing blood everywhere. She is okay – just very traumatised.”
The man was then detained by officers, who had pinned him to the ground, said witnesses.
One person was taken to hospital.
Police cordoned off a large area, and forensic officers were carrying out an investigation at the scene.
A fire extinguisher and a jacket were among the objects on the ground below the window.
Witnesses described terrifying scenes as they wrote about the incident on social media.
One witness wrote on Twitter: "Shush Apartments just off Swan Street. Blood on the windows and a car with caved in roof.
"Something bad’s happened here."
Another wrote: "Reports of man jumping from a building on the corner of Cross Keys Street & Swan Street in the Northern Quarter at around 8.15am.
"Landing on a car with driver and passenger."
Witnesses said five police vans and two ambulances were at the scene.
A Greater Manchester Police spokesman said: "Shortly after 7.40am on Tuesday, police were called to reports that a man had jumped from a second-storey flat window on Swan Street.
"A short time later, we received further reports that a number of people had been assaulted.
"Police then gained entry to a flat and found the body of a woman.
"A 37-year-old man was arrested nearby on suspicion of murder. He remains in custody for questioning."
Superintendent Chris Hill, of GMP’s City of Manchester team, said: “We are currently working to establish the exact circumstances surrounding what has happened this morning and the woman’s death.
“Her death is currently being treated as suspicious and we have a team of officers working at the scene.
“We are in the very early stages of our investigation however I would urge anyone with any information to please get in touch.”
A spokeswoman for the ambulance service said they were called to the scene and a person has been taken to Salford Royal Hospital.
A spokesman for Shush apartments told the Manchester Evening News that bosses were aware of a "major incident" at the flats, but would not comment further.
The Shush Apartments contain several serviced flats on the corner of Swan Street and Cross Keys Street.
The building’s website says the flats offer "touches of extra luxury, especially in the bedroom and bathrooms in the form of high quality memory foam mattresses for ultimate comfort and Jacuzzi baths".
It adds: "Allowing for both business clients during the week or leisure travellers at the weekends, they are popular with those seeking a location that is ideal for access to all areas in Manchester as well as one that offers an abundance of recreational opportunities."
