'Sadistic' killers left a dead deer with a tree branch shoved up its bottom and a McDonald's paper bag over its head.

The animal was discovered in Datchet, Berkshire, by a walker, who described the scene as 'disturbing and disgusting'.

It was found just before a young girl, aged eight, discovered a dead dog with a rock forced into its mouth and a concrete slab dropped onto it just a mile away.

Shouvik Chatterjee, 42, called the RSPCA as soon as he found the deer, and believes it had not been dead long.

He said: 'I thought it was somebody's dog just relaxing there but it was very disturbing and disgusting. It did shake me up.

'The poor animal, the face was covered with a McDonalds paper bag, it was completely covered and there were flies all over it.

'The worse part of it was it looked like somebody had forced a tree branch up the backside. That was really gross.

'It was very disturbing, that was why I did not share the picture, even to my wife.

'It was very sadistic. Why would you do that to an animal?'

After contacting the RSPCA, Mr Chatterjee, who works for a software company in Reading, Berks, was told to stay with the animal.

But he was soon called back and told it could not be collected until the next day as there was no one available.

Thames Valley Police are investigating the incidents and have appealed for anyone with information to come forward.
