(CNN) -- A Dutch documentary about a mentally ill and potentially dangerous 18-year-old has prompted lawmakers in the Netherlands -- amid national outrage -- to re-examine the treatment of those in psychiatric care. The documentary, which was produced by the Lutheran-run Evangelical Broadcasting Company and aired on public television Tuesday, followed Brandon van Ingen, a patient at a mental hospital in Ermelo. Since 2007, van Ingen has spent part of his days tethered to a wall due to the danger he poses to others, according to State Secretary for Public Health Marlies Veldhuijzen van Zanten-Hyllner. "Brandon's issue is so serious that he must be restricted in his freedom for the sake of his own safety and that of others," van Zanten-Hyllner wrote in a letter to parliament. "Because of this, Brandon consistently makes use of a band that he fastens himself when he is in the presence of his attendants and other visitors. Whenever there is no one present and at night, the band is loosened."
