German
 police were left speechless at the weekend when they stopped a group of
 inventive revellers cruising around town in a unique swimming pool-car.
The water wagon was spotted careering along Eibenstock near Chemnitz, southern Saxony, by a lone police sergeant on motorcycle.
'I
 saw the strangest-looking convertible I have ever seen - a roofless 
BMW, without registration plates, bordered around the open top with 
wooden boards and fake plastic flowers. It was also full of water,' he 
later said.
Aside from the driver, the car held three young males
 clad only in swimming trunks - one of whom was lolling on the boot with
 his feet dangling down into the vehicle. 
'All of them appeared drunk,' the police said.
The sergeant ended up chasing the BMW as it sped off into a car park - losing much of its liquid load as it went.
The
 young men sloshed to a halt and jumped out, fleeing across a nearby dry
 riverbed, where they hid as police swarmed around the vehicle.
It
 turned out the DIY car crew had hollowed out the inside of the vehicle,
 sealed and waterproofed it, painted it swimming pool blue and filled it
 with water for a grand day out.
Concerned that the men would try to 
return and make a getaway, the sergeant let the air out of the tyres and
 disconnected the spark plug leads.
Eventually the driver returned to
 fetch his belongings from the boot. The visibly intoxicated 
27-year-old, who said he hadn't been driving the unregistered vehicle, 
was allowed to get his shoes and wallet in return for a blood sample.
Police
 said they were investigating the man on suspicion of drink-driving and 
of driving an uninsured, unregistered vehicle.  Whether or not driving a
 car filled with water is an offence is something prosecutors are 
studying.
