Engineers fill sinkhole that reopened in Florida

Engineers have started to fill in a sinkhole in Florida that reopened two years after it swallowed and killed a man while he was sleeping in his home.
Crews sprayed water into the 20ft deep hole in Seffner, east of Tampa, before dumping gravel inside.
Officials believe heavy rains in the past month caused hydraulic stress on the patched sinkhole.
In March 2013, Jeffrey Bush was asleep in his bedroom when the floor collapsed and he fell into the sinkhole. His body was never recovered.
Florida is prone to sinkholes because there are subterranean caverns in the limestone, a porous rock that easily dissolves in water.
