I calculate at least an 80% probability that the incident happened in Vietnam.
The CCTV video from in front of a spa shows two women sweeping the pavement, when a little girl eager to play enters the view. She moves around, and eventually grabs a hold of a low hanging power line. That doesn’t do anything, because she’s not grounded, but when she grabs a metal post with her other hand, the circuit is closed and she gets zapped.
The electric current causes her body to tense up and unable to release the grip on the cable and post. Motorcycles ride by, the two women continue to sweep, and as the girl is being electrocuted, nobody notices, until she apparently loses consciousness and her right hand lets go.
Eventually the preggo sweeper who’s the nearest the girl notices she’s not OK and comes to her aid, alerting the other woman and they hail down a motorcycle to get the girl to hospital.
I don’t know the outcome, but hopefully she survived it.
Props to Best Gore member @african-angel for the video:
