Hi
Best is for her to move to a friends place ASAP., at lease a couple of weeks. She will get over the trauma.
If the place she is living is not safe, move to a safe location.
When Rascals come with guns etc, best give what you have without arguing with them. Insurance will take care of the replacements. In case if the Rascals got the house keys, consider new locks.
Often the holds up are organised by the Security or possible with house maids.
When you are driving home, please check be vigilant who is behind you on the road, do not go out after 6 p.m in Lae
