Staffordshire Trust has been forced to apologise after a baby was found with a dummy taped to its face.
Mid Staffordshire NHS Foundation Trust said a member of staff has been suspended and police are investigating.
The trust is at the centre of a public inquiry into serious failings of care with a report due to be published on the 6th February.
Statement from Mid Staffordshire NHS Foundation Trust:
"We have a zero tolerance approach to poor patient care and we take immediate, appropriate action as soon as we know about any potential serious incidents which happen in our hospitals.
"We are proud that our staff now feel confident to report any incidents which happen. We will continue to encourage staff to do this, and will continue to report incidents, even before they have been fully investigated, despite any negative attention this may create.
"One of our recent incidents involved a dummy that was found taped onto a baby’s face. Fortunately, the baby was unharmed. The incident is under investigation by the Police and so we are unable to give any more information at the moment.
"A member of staff has been suspended pending the outcome of the Police investigation and the Trust’s investigation under our disciplinary policy.
"We cannot emphasise strongly enough that this incident is exceptional and apologise again to the family. We want other hospitals to learn from this incident so that we can be sure that it does not happen to any other baby."
