Gudmundur Karl Arthorsson

Video has emerged of the aftermath of the drunken outburst, which shows Icelandair crew and passengers tying up duty free liquor enthusiast Gudmundur Karl Arthorsson. Warning: there is a lot of feeble moaning ahead.

"Gudmundur likes to drink, but his behavior has the family scratching their heads," one relative said. "He isn't a violent person. This was not normal behavior for him. I hope he is OK."
