Police say a drug deal gone wrong is behind a stabbing incident in NDG early Saturday morning.
Two men, one 20-years-old and the other 18-years-old, stabbed each other in an apartment on Monkland Ave. around 1:30 a.m., police say.
The 20-year-old old is in critical condition in hospital, while the other man sustained minor injuries.
Police are trying to determine which of the two men started the disagreement.
