TASMANIA Police are examining hours of CCTV footage as part of an investigation into a fire that destroyed a building in Hobart's central business district.
The cause of the blaze at the Bathurst Street building in the early hours of Saturday morning has not yet been determined.
The damage bill has been estimated at more than $10 million.
Firefighters yesterday were still working to make the building safe, and the road is expected to remain closed today.
Detective Sergeant Mathew Adams said the investigation was still in the early stages.
``We have obtained a large amount of CCTV and we're still in the process of collating it,'' he said.
Police have spoken to some people but want to speak to others who were in the area between midnight and 4am on Saturday.
``There were people in the area, there's no suggestion whatsoever that they were involved but we would like to speak to those people,'' Detective Sergeant Adams said.
Police were expected to examine the building yesterday afternoon to try to determine how and where the fire started.
``We're looking at $10 million plus damage and so all resources are being utilised,'' Detective Sergeant Adams said.
The building housed the Bridges Bros toy store and the Girl Guides Tasmania office and shop.
