A man was threatened with a suspected gun outside a chemist, police have said.
Two 21-year-olds were arrested and released on police bail over the incident on the Stewartstown Road area of west Belfast on Thursday evening.
The PSNI said two men were outside the pharmacy at about 5pm when they were approached and a gun was produced and pointed at the third man.
Inquiries into possession of a firearm with intent to endanger life and conspiracy to rob are continuing.
A report on one of the arrested men is being compiled for the Public Prosecution Service.
