Rangers had to shoot the animal because it had become dependent on human handouts.
A mass of wet wipes and plastic have been found in the stomach of a deer.
The grim discover was made at Bradgate Park in Leicestershire and prompted them to issue warnings on Twitter.
They've asked visitors to the park to dispose of litter responsibly and also not to feed the deer.
This one had been approaching people, and therefore the litter they left, because it was used to being fed.
