Detectives in Belfast are appealing for help in catching the men behind two separate robberies carried out at knifepoint.
In the first incident, police were called in after a robbery in the Lisburn Road area of south Belfast on Tuesday evening.
At around 6.30pm a man entered the premises and threatened a staff member with a knife. He then fled with a sum of money.
Meanwhile, detectives in the east of the city are also investigating a robbery in the Cregagh Road area, also on Tuesday evening. A man entered a business at around 9pm and threatened a staff member with a knife, before making off with a sum of money from the till.
It is understood police do not believe the two incidents are linked.
They have appealed to anyone who witnessed either robbery or who has information on them to contact investigators on 0845 600 8000.
Alternatively information can be reported anonymously to independent charity Crimestoppers on 0800 555 111.
