A 57-year-old man was arrested on suspicion of a number of offences including obstruction and fraudulent evasion of duty on fuel.
Mr Haslett said using a heavy goods vehicle as a weapon could “easily have caused catastrophic injury or worse”.
“These were local officers from a neighbourhood policing team carrying out their duty to keep communities safe from organised criminality,” he said.
“An investigation into this incident is now under way and we are liaising with our An Garda Síochána colleagues.
“We are particularly interested in locating the vehicle and the driver which rammed the police car. It was displaying the number plate LD08POP and crossed into the Republic of Ireland and will be bearing damage to the front driver’s side.
“We are appealing to anyone with information about this incident to contact us on 101 quoting reference number 754 of 5/03/21.”
