Man swallowed by Florida sinkhole

A man is presumed dead after a sinkhole opened up under his bedroom in the US state of Florida and "swallowed" him.
CNN is reporting that the incident happened overnight in a suburb of Tampa.
His 36-year-old's brother heard screams and tried in vain to pull him out.
Authorities called to the scene found the hole to be about 100 feet in diameter and were unable to make contact with the victim.
A spokesperson for the fire authority said the hole was still actively developing and was not man made.
Authorities have evacuated the neighbourhood as a precautionary measure.
