CCTV captured the moment an ambulance was broken into near Frankley, while paramedics were inside a property nearby treating a patient.
The break-in happened on Frankley Beeches Road at the junction of Egghill Lane at around 9pm on Sunday, October 28.
The ambulance crew was treating a patient inside a nearby property and returned to their locked ambulance to find the driver's side window had been smashed, and a variety of personal items including an iPhone stolen.
Nathan Hudson, the trust's emergency services operations delivery director, said: "I cannot begin to understand why someone would do this to an emergency blue lighted vehicle which has the sole responsibility of helping people.
"It really does make you question the morals of some people. This despicable crime has meant an ambulance is off the road and unable to respond to 999 calls whilst it’s being repaired; money which would’ve been better spent elsewhere in the service to help respond to patients.
“It is unacceptable that ambulance staff, who are there to help people in their hour of need, are made to suffer by members of the public.
"Any type of attack against our staff and our vehicles will not be tolerated.
"I am just thankful that, on this occasion, my staff weren’t hurt. If you are able to help to solve this crime, please come forward.”
The incident was captured by the ambulance's external cameras.
Anyone with information on the break-in is urged to contact West Midlands Police on 101, quoting crime number 20bw.
