Two people in critical condition after 'cruel' arson
Two people are in a critical condition following a fire at a house in Dungannon.
Police officers rescued a man aged 37 and 70-year-old woman along with two children, aged seven and 10, from the house in Cunninghams Lane on Monday night. The children are in a stable condition.
A 21-year-old man has been arrested on suspicion of arson after being found on the roof of the house.
Deputy Chief Constable Bobby Singleton said police are not currently treating the incident as a hate crime.
'Mindless cruelty'
Eight Police Service of Northern Ireland (PSNI) officers were treated in hospital for the effects of smoke inhalation but were later discharged.
Speaking on Tuesday afternoon, Singleton praised the officers' bravery, and said were it not for their actions, lives would have been lost.
He added the fire was started deliberately.
"It's hard to comprehend the mindless cruelty of this act, and the panic and fear caused to those in the home," he said.
He confirmed that officers responded to a report of children trapped in a house just after 20:30 GMT on Monday.
Police were the first emergency responders on site, at which point the fire was well alight, he added.
Two ladders were then obtained from nearby properties, and officers rescued two adults and two children, including an unresponsive 70-year-old woman.
"The adults remain in a critical condition in hospital today, while the children, thankfully, as we understand are presenting in a stable condition," Dep Ch Cons Singleton said.
He said he was aware of images and videos of the incident are circulating online, and urged people to not share it.
Earlier, Supt Peter Stevenson said a fifth person, who was found on the roof, was brought to safety. He was arrested on suspicion of arson with intent to endanger life and remains in custody.
Supt Stevenson said he was extremely proud of the eight officers, and all their thoughts are with those who remain in hospital.
"We want to thank the residents of Cunninghams Lane for their assistance with this terrible incident, which was undoubtedly traumatic for all involved," he added.
"The community will continue to see the presence of the emergency services in the area, as we proceed with our investigation into the cause of this fire."
Children crying for help
Cadalia Freitas was in her home nearby when her brother, who had left to go to work, raised the alarm.
She called the police before rushing to the house, where Ms Freitas heard children crying for help. Police arrived soon after.
She directed an officer with a ladder to the window, who helped rescue them.
Ms Freitas said she was "scared" and "traumatised" after witnessing the incident, and struggled to sleep as she smoke in the area made her cough.
'Cold light of day'
David Thompson, principal of Dungannon Primary School, told BBC News NI that the two children attended his school.
"We just think of the trauma that those children have gone through," he said.
"As a school community we want to get the message out there that we will be with those families to help and support them."

There is still the smell of smoke in the air on Tuesday morning in the Cunninghams Lane area of Dungannon.
In the cold light of day, the full extent of the damage caused by the house fire can now be seen.
Black scorch marks are etched on to the exterior walls and there is a broken upstairs window, with a ladder still perched on it. It was used to rescue those inside.
A police car and police cordon remain at the scene.
The local primary school is just around the corner. Dozens of school children have been walking past the cordon starting at the aftermath of the fire.
Democratic Unionist Party councillor Clement Cuthbertson said: "There were a number of videos of the fire on social media, and to be honest they were horrific.
He praised the brave actions of the police officers who managed to get the people out of the house before the fire brigade arrived.
Sinn Féin councillor Deirdre Varsani said she hoped that everyone caught up in the blaze was now safe.
The Northern Ireland Ambulance Service said it despatched six emergency crews, one hazardous response team, two paramedics and an ambulance officer.
Following assessment and initial treatment at the scene, 12 patients were taken, by ambulance, to Craigavon Area Hospital.
