A 20-year-old man has been tied up and threatened at knifepoint during a robbery in west Belfast.
It happened at a house in the Cloona Manor area during the early hours of Sunday morning.
The victim was not injured but was left shocked by the ordeal, police said.
The robbers stole a wallet and car keys before fleeing in a silver Vauxhall Vectra.
The car was later recovered by police after being involved in a crash on the Crossgar Road in Saintfield shortly after 3am.
Two men aged 18 and 19 arrested on suspicion of robbery and a number of other offences remain in police custody.
The Police Service of Northern Ireland (PSNI) has appealed for any witnesses to contact detectives at Musgrave Street on 101.
