A man in the US state of Florida has disappeared into a massive sinkhole that swallowed up a bedroom in his house.
Rescue crews have not made contact with the 36-year-old and he is presumed dead.
The man's brother told rescue crews he heard a loud crash, then his brother screaming for help.
Local police say first responders could only see part of a mattress sticking out of the hole.
Officials in the town near Tampa have postponed rescue efforts until they determine how much ground under the house is compromised, and neighbours have been evacuated.
Officials say sinkholes are common in certain parts of Florida, which sits on a system of caverns which can collapse.
