A dog mauled an elderly man and ripped off a "chunk of his arm," leaving his bone exposed during the savage attack. The incident took place last week in a park in Derby, England.

Charles Brown, 82, was left bleeding after the attack carried out by a "black, muscular Labrador." According to local media reports, the owner of the dog fled the scene when it attacked the man.

"He’s had his injections, you’ll be fine," the owner said as he ran from the site. Brown managed to call wife Ann, 74, who rushed him to a nearby hospital. Doctors told him he would require a skin graft to repair the damage.

"The force of the dog was indescribable and it knocked me over onto my back. My lower body is all bruised, my back is twisted, and the flesh of my arm was nowhere to be seen... I don’t know if the dog ate it or not, but it was gone, I remember laying in bed that evening and noticing how much flesh was gone," Brown said, according to U.K.'s Metro.

"He leapt straight for my neck so I put my arm in the way and he got a hold of that, when I looked down after being slammed to the ground, I could see bone," he said, recalling the attack. "I knew it was serious... My arm was bleeding continuously, there was so much of it and the man whose dog attacked me had already made his escape... It’s a good thing that I’m OK, my biggest worry now is what if it happens again to a small child, I’m not sure they would be able to defend themselves so it could be fatal."

Brown's wife also reacted, expressing concern about dog attacks.

"I just can’t believe the man abandoned him, it’s disgusting, we want to find the culprit before this happens again," Ann said.

Derbyshire police confirmed the attack and urged anyone with information about the dog owner to contact authorities. It remains unclear if charges will be filed against the dog owner. The fate of the dog also remains unknown.
