A driver has been arrested after a sick incident in which a dog was tied to a Porsche with a length of rope and dragged along for six miles.
The 33-year-old man from Worthing, West Sussex, handed himself in last night and has been held on suspicion of animal cruelty.
The beagle collie cross died of terrible injuries after being pulled at speeds of up to 70mph along the A27 close to Brighton, East Sussex.
Its mangled body was eventually dumped in a lay-by and the brutal motorist drove off.
Officers found the battered corpse behind a Tesco store in Brighton, East Sussex, late on Sunday night.
Detectives believe the vile episode was deliberate.
The alarm was raised at 10pm on Sunday night, when a bystander dialled 999 after seeing the black Porsche 911 Carrera towing the terrified beagle through a car park at Devil's Dyke beauty spot.
Half an hour later, police received another call to say the driver was heading along a nearby dual carriageway, with the dog, now clearly dead, still attached to the car.

After discovering the beagle's abandoned body, officers took it to a local vet for examination and identification.
PC Scott Walters said: 'This is being treated as a deliberate act. Anyone who can help us find those responsible must get in touch.
'The injuries this dog suffered were horrific. It has been distressing for everyone involved.'
The dog was identified but police have not yet been able to get in contact its owners.
An RSPCA spokeswoman said the dog's body has been kept as evidence.
She said: 'We would very much like to help the police with this matter and to hear from anyone who saw this horrific incident or who might have taken a note of the car's registration plate.
'This was an unbelievable thing to do to an animal. It would have suffered both physically and mentally during its ordeal.'
A solicitor representing the 33-year-old added: 'My client is now very worried because of all the Facebook messages and threats of retaliation that have been made on the internet.
'He handed himself into police expecting everything to be cleared up easily. His Porsche is still with forensic officers.'
Police were testing the car to see if the chain was attached deliberately.
