'Neglect' care workers cleared.
The prosecution offered no evidence in the case against Catherine Flowers, aged 56, and Donna Reid, aged 31, when they appeared before Wolverhampton Crown Court.
The two women, who work at the Grange House home in Parkway Road, Dudley, had both denied ill treating or wilfully neglecting a person suffering from a mental incapacity.
Judge Nicholas Webb directed not guilty verdicts should be recorded and said the ordeal suffered by 51-year-old Erroll Collins must have been "dreadfully distressing".
"This brings to a close the criminal proceedings against you," he told the women. "However, it does not bring to a close any employment sanctions which may or may not follow."
Flowers, of Rangeways Road, Kingswinford, and Reid, of Peak Road, Stourbridge, are now set to face a disciplinary hearing brought by Dudley Council.
They were charged after Mr Collins who has the mental age of a six-year-old, failed to return to the home following a trip to a centre in W alsall.
