Israeli police arrested the military's former top lawyer Yifat Tomer-Yerushalmi, the national security minister said Monday, after she admitted to leaking a video appearing to show soldiers abusing a Palestinian detainee.

Former advocate general Tomer-Yerushalmi disappeared for several hours on Sunday after announcing her resignation, triggering media speculation of a possible suicide attempt, but she was later detained.

According to a copy of her resignation letter published by Israeli media on Friday, Tomer-Yerushalmi has acknowledged that her office had released the video to the media last year during an international uproar over prisoner mistreatment.
