Two suspects on e-scooters approached an 18-year-old man and told him to hand over his phone at around 5.15pm on Tuesday, 2 February.
When the victim refused, one of them pointed to his pocket and claimed to have a gun.
However, the man did not see a firearm and refused to hand over his phone.
Five minutes later the two suspects approached a 17-year-old male in the park and again asked him to give them his phone.
When he refused, one of them threw acid over his face and they both made off in an unknown direction.
The victim was taken to hospital where he continues to receive treatment. His condition is not thought to be life-threatening.
Both suspects are described as black and around 17-years-old. One of them was wearing a white hoody and blue jacket while the other was wearing a black jacket and hat.
Plashet Park is closed and a crime scene remains in place.
Anyone with information about the incident should call police on 101 or tweet @MetCC and quote CAD 6803/2Feb.
