Staff at Middlemore Hospital were gutted to find that more than 10 cars had been broken into just before Christmas.
Video posted online shows a line of cars with smashed rear windows and side windows at a council-owned car park near the hospital.
It is understood that the damaged cars were mostly owned by Middlemore staff. The car park on Swaffield Road is not guarded by security.
On social media, one person who had their car broken into said they were uninsured.
Another person said some hospital staff whose cars were damaged "broke down and cried" because it had added to the Christmas stress they were feeling.
