Hans was arrested on November 30, 2011 near a BCI Bank in Macul after an explosive attack. Held in preventive prison under the Anti-terrorist Law, he was charged for installation of another device in memorial of Jaime Guzman. After a year in prison, Hans was granted house arrest and went underground on December 7, 2012 after his legal process was effectively sabotaged by the state. On April 26, 2013, he was arrested by the Investigative Police (PDI). Hans was sentenced in July 2013 to 5 years in prison, and since then has carried out multiple hunger strikes, the latest in solidarity with Monica Caballero, Francisco Solar, Sebastian Oversluij, and Matias Catrileo.
