Paramedics have come under attack as they treated an assault victim in Coleraine.
The ambulance windscreen was shattered during the incident on Tuesday November 18 in the Mount Street area of Coleraine at around 8pm.
A gang of up to 10 men surrounded the emergency vehicle and then the crew heard the front windscreen being smashed.
They called the police as they feared for their safety.
A spokesman for the Ambulance Service said: "This incident highlights the commitment of NIAS crews to helping those in need, while at the same time having to put their own physical and mental welfare to the side.
"When they arrived on scene and it was safe for the crew to leave their vehicle, it became clear that another incident had occurred in the street resulting in a person having been stabbed.
"Another ambulance was sent to the scene while the crew who moments earlier were taking refuge in their vehicle immediately tended to the victim of the stabbing."
Police confirmed they attended the scene and made two arrests.
Chief Inspector Nicky Thompson said: “Police responded to a report of damage caused to an ambulance and around ten people having gathered around the vehicle. The situation quickly de-escalated when police arrived.
We established that we were also dealing with a stabbing incident when a man who was at the scene presented himself with wounds to his back. He was taken to hospital for treatment but his injuries are not thought to be life threatening
“Officers arrested two people in relation to the stabbing incident and the damage caused to the ambulance. An 18 year old male was arrested on suspicion of grievous bodily harm and possession of an offensive weapon.
"A second male, aged 17, was arrested for common assault and criminal damage. The investigations into both matters are continuing.”
The crew were then tasked to deal with a stabbing after a man who was at the scene presented himself with wounds to his back.
The victim was taken to hospital for treatment for injuries not thought to be life threatening.
The Ambulance Service highlighted that attacks like this impact their capacity to respond to life-threatening calls and that they need the support of the community to ensure staff are kept safe.
