Two men charged with attempted murder have been remanded in custody at Belfast Magistrates' Court.
The charges relate to a stabbing in Belfast city centre on Monday.
A man in his 30s was said to be in a critical condition after he was allegedly attacked near Royal Avenue.
Samuel Robinson, 25, of Agnes Street, Belfast and 18-year-old Stephen Smyth, of Ormeau Centre, Verner Street, also in Belfast appeared in court on Wednesday.
A police officer said she could connect them with the alleged offence and confirmed CCTV footage had been examined as part of the investigation.
A lawyer for Mr Smyth said his client had no knowledge that a knife was used in the incident.
It was also disclosed in court that police are seeking a third person in connection with their inquiries.
Neither of the accused applied for bail and they were remanded in custody to appear in court again later this month.
