Alligator rips off woman's arm

An alligator has ripped off an elderly woman's arm in a Florida canal.

Joy Hill, a spokeswoman for the Florida Fish and Wildlife Conservation Commission, says the woman was in a critical condition.

The Lake County sheriff's office said the victim was 84-year-old Carol Hough.

Ms Hough's neighbour, Delmas Zickefoose, told the Orlando Sentinel that he saw Hough flailing in the 4ft-deep canal that runs behind their mobile homes.

It was not clear how Ms Hough ended up in the water.

The alligator will be killed so authorities can perform an autopsy.

The attacks are not uncommon: a teenager lost part of his arm to an alligator in July, and an airboat captain lost a hand while feeding one in June.
