The BBC report:
The number of West Midlands Ambulance Service (WMAS) staff assaulted while working has fallen by 16% in a year.
A Freedom of Information (FOI) request found the number of recorded physical attacks on staff fell from 210 to 175 between April 2012 and March 2013.
The Unison union said it was concerned the figures were not accurate because not every attack was being reported.
