Long-lost members of an Austrian family terrorised by decades of imprisonment had an “astonishing” reunion at the clinic where psychiatrists are helping them cope.

Long-lost members of an Austrian family terrorised by decades of imprisonment had an "astonishing" reunion at the clinic where psychiatrists are helping them cope, authorities said today.

Horrified residents in the Austrian town where a 73-year-old man imprisoned and repeatedly raped his daughter for 24 years are questioning how he deceived police, neighbours and social workers for so long.

A woman was held captive in a cellar for almost 24 years by her father, who repeatedly raped her and fathered at least six children, police said.
