A researcher at a station in Antarctica stabbed his colleague after allegedly suffering an emotional breakdown that caused him to attack his partner.

The stabbing occurred on Oct. 9 at Russian Antarctic station Bellingshausen on King George Island, The Associated Press first reported Tuesday, citing Interfax news.

Engineer Sergey Savitsky, 55, stabbed his 52-year-old colleague, Oleg Beloguzov, in the chest, the Mirror reported Wednesday.

The attack resulted from “tensions in a confined space,” according to the AP.

Beloguzov was immediately taken to the closest hospital in Chile and remains in critical condition, according to the Mirror.

Savitsky and Beloguzov had been working and living together for six months at the station prior to the stabbing, Newsweek reported.
