Greater Manchester Police (GMP) have released the identities of the four men for the first time since the remains of three victims were recovered from the building in Oldham. Officers said Nam Thanh Le, 21, arrived in the UK in January and was last in touch with his family in Vietnam on May 4 – three days before the massive fire that destroyed Bismark House Mill. Le had told relatives he was living in a ‘mill’ in ‘Dam’ – believed to be Oldham – while looking for work. The other three men believed to have died in the fire were Cuong Van Chu, 39, Uoc Van Nguyen, 31, and Duong Van Nguyen, 29. Two of the men, Chu and Uoc, last spoke to the families them on the day of Fire. Det Supt Lewis Hughes, GMP’s victim identification officer, said: “Our thoughts remain with Cuong, Uoc, Duong and Nam. “Specially trained officers have been in direct contact with them and continue to make every effort to ensure they are fully informed and supported in Vietnam as they would be in the UK.” Detectives are investigating how the fire started at the mill. It took firefighters four days to put it out, during which time authorities believed no one was inside. The mill housed several companies, including a tile factory and a laser game center. There were also serviced offices and storage facilities on site. Firefighters did not enter the mill at the time due to safety concerns about the structural stability of the building. It wasn’t until July 21 – 10 weeks after the fire – that police were tipped off that people might be inside the mill after the family of one of the men contacted a Catholic church in London asking for help. The first human remains were found two days later. The remains of a third victim were found earlier this week. Police said Cuong Van Chu regularly spoke to his wife and children by phone, but they had not heard from him since May 7, the day of the fire. It arrived in the UK in June 2019. Uoc Van Nguyen was also in regular contact with his wife and last spoke to her on the day the fire broke out. He had told her that day that he was in a mill. Duong Van Nguyen last spoke to his family about three months ago, police said, when he told them he was living in “an abandoned house” while looking for work. It arrived in the UK around August 2021, officers believe. Detectives are in the early stages of piecing together the men’s lives, including how they got to the UK and how long they were inside the mill. They are also investigating how the fire started and the activities at the mill beforehand. One of the lines of inquiry is whether an illegal cannabis plant was operating inside the building, however it is not known if any such activity is connected to the fire or the victims. Hughes said: “While we have reason to suspect that Cuong, Uoc, Duong and Nam may have been at the mill during the fire, we are keeping an open mind about the number of people present and their whereabouts. I am therefore appealing for them or anyone with information on their whereabouts before or after the fire to contact us. I stress that their safety and well-being is our number one priority.”
