A large sinkhole opened under the bedroom of a house near Tampa, trapping a 34-year-old man in the rubble.
    
The home collapsed late Thursday in a Brandon neighbourhood. By
early Friday, Hillsborough County Fire Rescue officials determined the home had become too unstable to continue rescue efforts.
    
Fire rescue spokeswoman Jessica Damico says Bracken Engineering officials determined the home's bedroom is the centre of the sinkhole, which measures about 100 feet across.
    
Engineering officials will return later Friday morning with more sophisticated monitoring equipment to determine the actual diameter and depth of the sinkhole.
    
Reports from the scene say the man's brother tried to pull him from the sinkhole. An arriving deputy was able to pull the brother from the still collapsing sinkhole.

The 34-year-old man has been presumed dead.

Police have started to evacuate the neighbourhood as a precaution.
