Police have arrested a 17-year-old girl on suspicion of arson following a fire at a derelict pub in Newport.
Crews were called to the Centurion Inn on Heather Road just after 7pm on Thursday evening.
The pub is near many homes and people were advised to keep doors and windows closed. Fire crews say no-one was hurt or injured in the fire.
In a statement, Gwent Police said they are "treating the fire as suspicious". Police have launched a joint investigation with South Wales Fire and Rescue service.
Six fire crews were sent to the scene. They had left by Friday morning after getting the fire under control but will return later.
The Centurion Inn was due to be demolished to make way for 10 affordable homes.
There had been a petition to save the pub which was signed by more than 600 people.
