Vienna  - Vienna theatre artist Hubsi Kramar has been getting police protection after far-right politicians and tabloid media blasted his planned play about the incest case of Josef Fritzl.

Kramar, 59, defended himself in a press conference on Thursday, saying that his production about the man who imprisoned and raped his own daughter for 24 years would not be a comedy, but would satirize the "hypocritical" media coverage of the case.

"The play describes a certain process in Austria's mental state," Kramar said.
