An investigation has been launched after an ambulance crew member was attacked by a man wielding a knife in Camden.
The ambulance crew had parked their vehicle after taking a patient to University College Hospital just before 7.55pm on Monday.
A male crew member, standing outside the vehicle, was approached from behind by a man who pushed a knife against his back.
The victim was able to defuse the situation and the suspect eventually backed away, placing the knife in a bag and fleeing the scene.
Police are keen to hear from anyone who knows who the man is.
