A  Polokwane based Roman Catholic nun committed suicide after a videotape of her breaking the most sacred vow of celibacy found its way to the public.

The 28-year-old nun was recently filmed engaging in sex with the parish priest.

Sister Ntando Mlilo of the Polokwane diocese was caught on CCTV. The video was later deleted due to how grubby it is.

The video shows the pair having a good time in the office. Judging from the incident, the two seem to have been doing it for a while.

The shame and embarrassment of the incident eventually led to Sister Ntando committing suicide by overdosing on  pills.

When hinnews.com contacted the head priest at the branch, he refused to comment but acknowledged he knew of the existence of the tape.
