A 22-year-old man is in a stable condition after he was violently stabbed in Alexandra overnight.
The man was flown to Dunedin Hospital in a serious condition after the alleged offender attacked him with a knife at around 11:30pm on Wednesday.
In a statement on Thursday afternoon, a police spokesperson said officers believe the man was attacked following a confrontation with the alleged offender.
The men, who are known to each other, had been involved in an incident earlier in the evening, the spokesperson said.
The 22-year-old has undergone surgery and remains in hospital.
Authorities are aware of the suspect's identity and are calling on him to come forward.
"He is aware that police wish to speak to him. We encourage him to contact us immediately, and would discourage others from assisting him by transporting or hiding him from police," Detective Sergeant Derek Shaw said.
It's believed the man fled the immediate area and may have travelled to Southland.
Anyone with information which can assist with this investigation is urged to contact police on 105 quoting file number 210225/1718, or ask to speak to Detective Sergeant Derek Shaw.
