I can tell you didnt read the article. Let me help you out by quoting a relevant bit here:
You think I summed up what happened according to the article without reading it? Lol
Another official mentioned the involvement of seven to eight youths.
It typically only takes at most 3-4 people to effectively restrain a grown man. That leaves another 3-4 to restrain and rape his wife. It seems they had sufficient numbers to achieve this with little trouble, even if they were unarmed. And I see no reason to assume they'd have been unarmed. Put a knife to his throat and it only takes one person to restrain him.
If had to choose between a trip to the hospital or watching my wife get raped, I'll take the trip to the hospital. I reckon living out your life knowing you did nothing is worse.
Thanks for clearing it up, no idea why the article didn't mention him.
