Anger at 999 staff suffering violence
Almost 30 per cent of ambulance staff in the West Midlands and Shropshire experienced violence at the hands of patients during the last year.
A further 38 per cent were verbally abused by patients over a 12-month period in 2008/09, health chiefs said.
Anthony Marsh, West Midlands Ambulance Service Trust chief executive, said the abuse was "appalling" and the service would do all it could to stop the problem.

He said: "The figures speak for themselves - 27 per cent of staff said they had experienced violence from patients and 38 per cent said they had suffered verbal harassment from patients.
"These figures are appalling. I find it sickening that staff should have to put up with such abuse."
The figures come as service chairman Sir Graham Meldrum praised staff in the build-up to the annual meeting, which is being held at Shirehall, Shrewsbury, next Wednesday.
Sir Graham said staff had made "superhuman efforts" to ensure patient safety during the year.
He said: "Staff have risen to the challenges and exceeded the results that could have been expected.
"There can be no doubt that the service was severely tested during 2008/9, but it is my pleasure to report to the people of the West Midlands region that their ambulance service performed to the highest of standards."
