An ambulance has been run off the road and another almost rammed twice, sparking safety fears for north Queensland paramedics.
The Queensland Ambulance Service has expressed their concern for the wellbeing of Townsville paramedics, saying it may end in tragedy if they continue to be targeted.
The QAS said staff have been left shaken after an ambulance responding to a patient at 3am on Tuesday was forced off the road by a car driving directly towards it.
Another car tried to ram an ambulance twice in the early hours of Wednesday, they said.
"I'm really concerned that this will end in tragedy if this behaviour continues," QAS Assistant Commissioner Matthew Green said.
"Our staff are good drivers but even good drivers can get put into situations that you just cannot recover from and a car driving on the wrong side of the road directly at you at 3am may just be that."
It comes after a woman told media on Tuesday of the moment her car was repeatedly rammed while out Christmas shopping in Townsville.
An emotional Melissa Young-Florence said she had "never felt so scared in her life" after being targeted by a group of youths last week.
Police said five patrol cars had also been rammed during a youth crime spike that prompted 28 specialist officers to arrive in Townsville this week.
"The last couple of weeks have been the most relentless and trying for the police in the community," Queensland Police Commissioner Katarina Carroll said.
Deputy Police Commissioner Shane Chelepy said up to 90 people had been arrested over the past 10 days. .
"The hard working police on the frontline are still there to support the community and keep the community safe," he said.
Deputy Premier Steven Miles said in Townsville on Wednesday he was committed to tackling youth crime in Queensland.
"The stories that I've heard here are harrowing and unacceptable and we don't ever want to see them in our community," he said.
