wharf rats they call them, but to me the devil's workshop they are! What on Earth should be the explanation of breaking the glass someone's van (bus), just to steal some some products?
This happened to me only recently (last week); the back glass was totally broken off, and about 25 pieces of the product (LCD and PLASMA all the way from the United Kingdom) stolen. Side mirror removed, and the ignition key totally destroyed!

What on earth could be the reason for this unkind attitude towards a fellow human? The products are misunderstood be gotten at cheap prices here (UK), which is far from the truth.

I weep for the country, because nothing seems to be working in her favour! I advice, the house to learn from my lesson and avoid such mistake ( or what ever it may be called).

Sorr for your loss man.
Fhemmmy is 100% right, don't load anything in a car that is not containerized. I had the same experience a couple of years ago, and I learned from it. Don't listen to whatever anybody may tell you that there's a way to do it and everything will be ok. There's only 2 ways to be safer, cars with goods should go in the container, cars without goods can go by Ro-Ro. However, having a trusted, experienced clearing agent is important too. On your side, before you ship a car, make sure you 've the cash for clearing at hand and send it to your agent soon enough to avoid cash strapped delay. Every minute your car spends in the wharf after being taken out from the ship increases it's chance of being vandalized.
When next you want to ship things to Naija, take your time, do your calculations well, spend a few bucks and make some calls. Just make sure that everything is lined up well.
