It pays to let sleeping caravanners lie - so a would-be thief discovered as he attempted to drive off with a van while the owner slept inside. The owner woke up in the middle of the night as he thought he heard chains rattling. He realised he wasn't dreaming when the caravan started moving. Luckily he had a mobile phone and was able to call police and give them a turn by turn update on where the van was headed. The incident happened in the New Zealand town of Petone, just north of Wellington. Police were quickly on the scene and were able to pull over the driver in a neighbouring suburb. The 36 year old alleged offender was charged with theft and firearms offences.
