Two people died after a fire broke out in a flat in a public housing estate in the Kwun Tong area of Hong Kong’s Kowloon district on Monday morning.

At 5am, Sing Pao reports, a fire started at a flat on the eighth floor of Sau Fai House, in the Sau Mau Ping Estate.

A 55-year-old man, believed to be a scavenger, was found dead in the kitchen. He is believed to have lived alone in the flat, which was packed with items that made it difficult for the firemen to perform a rescue.

Firemen also found a 66-year-old woman, surnamed Lam, who lived on the same floor, lying unconscious in the corridor. She was sent to hospital but was later pronounced dead later.

A 92-year-old man and 65-year-old woman felt unwell after inhaling smoke and were sent to the United Christian Hospital.

Firemen took one hour and 20 minutes to put out the fire and evacuated about 100 people. Nine fire engines and six ambulances were dispatched and 66 firefighters and paramedics were deployed in the incident, Apple Daily reports.

After initial investigations, firemen said there were no signs that cooking had been in progress. They will further investigate the cause of the fire, along with police officers.
