Personal life
On 5 July 2016, a rampage incident on Ragnar's home in Garðabær was notified to the police. When the police officers arrived to his house, Ragnar had left the scene but the apartment was in a bad state with ruined furniture. In a police report, Ragnar's then-wife asserted that he had threatened her. A few days later, Ragnar was brought in for questioning by the police where he denied all accusations of violence and threatening. Ragnar's neighbours, who had originally called the police, reported the incident the Football Association of Iceland (KSÍ), but no action was taken. The event was publicly revealed in September 2021 when several cases of violence by Icelandic professional footballers were exposed in the Icelandic media.[21]
