US police officers mock injured dementia sufferer after forcible arrest.
Karen Garner, 73, was detained while walking home after leaving a Colorado Walmart without paying for items worth around £9.
Appearing confused in the Loveland Police bodycam footage, an officer forces her to the ground before he and a colleague continue to manhandle the distressed pensioner.
She suffered a dislocated shoulder and fractured arm - to the amusement of the officers, who watched the footage while she was left in a cell without medical attention.
