Jakob, 24, and his brothers Filip, 31, and Henrik, 34, who are also Olympic athletes, made public claims in October 2023 that their father – who was their coach until 2022 – had been violent.
The trio, who are among seven Ingebrigtsen children, wrote at the time that they “still feel discomfort and fear” about Gjert, who they accused of being “very aggressive and controlling”.
Gjert, who stepped down as his sons’ coach in 2022, said at the time via his lawyer that statement was “baseless” and he “never used violence against his children”.
Gjert was charged with one offence in April – but five charges were dropped on the strength of evidence and one other because of time constraints. A further charge was later added to the case.
In addition to his two Olympic titles, Jakob is a two-time 5,000m world champion, two-time world 1500m silver medallist, and 11-time European champion.
At the weekend he won two world indoor titles taking gold in the 3,000m and 1500m in Nanjing, China.
