Dr Nav Ahluwalia, executive medical director for Rotherham, Doncaster and South Humber NHS Foundation Trust said: "We fully apologised to service users and their families at the time of the incidents and we apologise again today for the actions of the individuals that have been found guilty.
"The trust took immediate action as soon as we were made aware of the situation in 2007 and worked with South Yorkshire Police in their investigation into this matter.
"The trust has implemented improvements to the learning disability service at this centre to minimise the risks of such incidents happening again.
"We will not tolerate staff mistreating service users and have reinforced our channels of communication to ensure that staff, service users and carers report suspected abuse so that we can take action."
