The emergency services have found a woman and a man dead in neighbouring flats.
Paramedics made the discovery after being called to an address in south Manchester.
They found a dead woman in the property and then later discovered a man had passed away in a neighbouring flat.
A police investigation is now underway into both deaths, the Manchester Evening News reports.
Fire crews also attended the scene after reports of a gas leak, with nearby shops being evacuated.
A Greater Manchester Police spokesman said: "We were contacted by NWAS at about 4.20pm today (April 23, 2022) regarding a deceased female at an address on Princess Road, Manchester.
"Officers attended and while at the address were further contacted at 7.10pm in relation to a concern for welfare at a neighbouring flat.
