Two boys aged 12 and 14 have been arrested on suspicion of arson after a large fire in Nottingham city centre.
The incident happened just after 10pm on Monday at a building in Market Street, just above Escobar, Nottinghamshire Police said.
Two boys have been arrested on suspicion of arson and remain in police custody.
Smoke was seen billowing from the roof opposite the Theatre Royal.
At the height of the blaze, 12 fire engines were in attendance, along with ambulance service staff.
Officers closed Upper Parliament Street, Goldsmith Street, Market Street and the surrounding area to protect the public.
Some properties were evacuated while fire crews dealt with the blaze, police added.
Tram services were stopped and roads were closed throughout Nottingham city centre as firefighters battled the blaze at a residential property.
Several roads in the city remain closed, while many bus services have returned to their normal routes, but with delays.
Early on Tuesday morning, the Nottinghamshire Fire and Rescue Service (NFRS) said there were still some crews at the scene.
