Former Chilean dictator Augusto Pinochet has been fingerprinted and photographed as part of his indictment relating to the killing and disappearance of leftist opponents under his 17-year military dictatorship.

Police acting on a judge's order arrived at General Pinochet's Santiago mansion Wednesday to take the mugshots and fingerprint the 90-year-old former dictator. His lawyer, Pablo Rodriguez, described the procedure as an insult.

The charges stem from an event known as Operation Colombo, in which 119 political dissidents disappeared in the mid-1970s during his rule. General Pinochet ruled Chile from 1973 to 1990.

General Pinochet also has been indicted for tax fraud and other crimes related to some $27 million he allegedly hid in foreign banks. In recent months, Chilean courts have steadily stripped him of immunity from prosecution on a case-by-case basis. He has been under house arrest for five weeks.

In another development, a Chilean appeals court Wednesday upheld a life sentence imposed on a secret police chief who served under General Pinochet - former General Hugo Salas Wenzel.

General Salas Wenzel was convicted of killing 12 government opponents in 1987.
