Three managers of a privately-run nursing home in Surrey have been charged with wilful neglect and ill-treatment of residents.
Police said the charges related to allegations of neglect at Rose Hill Nursing Home in Rose Hill, Dorking.
Det Sgt Abigail Edey said it followed an "extensive and sensitive" inquiry.
Two proprietors of the nursing home, Tarlochan and Jasbir Chahal, and the nursing home manager, Kalsum Noh, are due in court next year.
Police said all three were charged under the Mental Capacity Act.
No-one at the nursing home was available to comment on Friday.
Mr Chahal, 63, and his wife, Jasbir, 58, both of The Park, Bookham, and Kalsum Noh, 60, of Boxhill Road, Tadworth, are due to appear at South East Surrey Magistrates Court on 7 January.
A spokeswoman for Surrey Police confirmed the Chahals were the proprietors of the home and the third person to face charges, Ms Noh, was the nursing home manager.
