A man expecting the arrival of his friend has accidentally buzzed three alleged thieves into his apartment in Melbourne's CBD.
The man told police he believed a friend was downstairs when contacted on the intercom of his Swanston Street building around 12.35pm on Tuesday afternoon.
Despite realising his mistake as soon as he opened the door, the man was unable to keep out the three alleged burglars.
The trio of thieves then allegedly stole his mobile phone and empty shopping bag from a table, then fled the scene.
No one was injured in the incident.
Police have released images of the three men they allege were responsible for the robbery.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000.
