A woman who suffers from a disease which causes balance problems was thrown into a cell - because police mistakenly thought she was drunk.
Lorraine Parkin, 37, who is teetotal, was driving away from a supermarket when an officer ordered her to stop her car.
Mrs Parkin was asked whether she had been drinking. The woman officer asked her to step out of her car and confiscated her keys.
Mother- of- three Mrs Parkin explained that she suffered from Huntington's disease, showed her medication and offered to take a breath test.
Police were nearby and at one stage up to ten officers surrounded her as they waited for a breath test kit to arrive.
She said that when a kit could not be found officers bundled her into the back of a van and took her to a police station where she was placed in a cell.
Huntington's disease is a progressive hereditary condition, which affects the body's nervous system.
Sufferers can have unco-ordinated movements and slurred speech, which make them appear drunk.
Mrs Parkin, from Swinton in Greater Manchester, was stopped after a police officer saw her walking to her car.
Last night, she accused police of discriminating against the disabled.
