Pedro Luis Gallego, better known as the “elevator rapist”, was arrested on Wednesday in Segovia, accused of four acts of sexual assault, two of which were attempted assault, El Mundo reports. The crimes happened in the area near La Paz (The Peace) hospital, now earning him the name of “the rapist of peace.”

Gallego was previously convicted in 1992 for killing two young women aged 17 and 19, as well as for committing 18 rapes and sexual assaults. He was sentenced to serve more than life in prison: 273 years.

During his attacks, he used his profession as an elevator mechanic to access the hallways of his victims, and then force himself onto them when they approached the elevator, thus earning him the name “elevator rapist”.

A European Court of Human Rights later overruled a Spanish doctrine that had restricted his ability to be released early, and he was then set free in 2013.

Gallego is not the only convicted rapist released in 2013 who to be arrested for re-offending. One man dubbed the “stiletto rapist” was arrested for attacking a woman just four months after his release, El Mundo reports.
