Ambulance crews working tirelessly to save lives round-the-clock have been attacked more than 1500 times in the last three years by members of the public.
Yorkshire Ambulance Service revealed there has been 1567 reported attacks on their staff across the county since 2013 - and the number of incidents is on the rise.
The most recent figures show 2015/16 recorded the highest number with 606 incidents. The year previous was 555, and the year before that was 406.
Dr David Macklin, executive director of operations at Yorkshire Ambulance Service NHS Trust, is now urging members of the public to restrain themselves and allow emergency crews to do their job.
He said: "The safety of our employees is of paramount importance and we operate a zero tolerance policy; action will be taken against anyone who assaults our staff.
“Ambulance service staff do a difficult job, often in challenging circumstances. Physical and verbal attacks on any member of NHS staff are completely unacceptable and we are doing everything we can to prevent them.
“We actively encourage staff to report all incidents of violent and aggressive behaviour and this includes any aspects of abuse however minor.”
YAS receives an average of 2,330 emergency and urgent calls per day."
Any incidents should be reported to police on 101.
