A young man and four youths have been charged in connection with a stabbing at a house party in the Southlands neighbourhood of St. John's earlier this month.

Robert Mills, 22, is facing charges of aggravated assault, assault with a weapon (brass knuckles), possession of a prohibited weapon and breach of probation.

Mills was on crutches when he appeared in provincial court in St. John's Monday.

On Sunday, the Royal Newfoundland Constabulary Major Crime Unit arrested Mills and four teenage boys, who cannot be identified because of their ages. 

The four youths were all charged with aggravated assault, and one was also charged with breaching his probation order.

Each of the accused was taken one-by-one into provincial court in St. John's Monday morning, while members of their families filed into the courtroom for the proceedings. 

Mills and the teens, who are between ages of 15 and 16, were ordered not to have contact with 27 people, including the victim and witnesses. 

Charges are 'what we had grounds for'

On March 4, a man, 21, was brought to hospital with serious injuries after he was stabbed at a house party on Mahogany Place.

RNC Const. Geoff Higdon said investigators launched a "very extensive interview" in relation to the assault.

Police have not said what kind of weapon was used, but said the injuries were consistent with that of a stabbing. 

Asked why charges of attempted murder were not laid, Higdon said "given what we had and the information and evidence we were able to gather, both forensics and conducting interviews ... the charges that we laid are what we had grounds for."

The man who was assaulted has since been released from hospital. Higdon did not provide an update on his condition. 

However, a family member of the victim told CBC News he is recovering. 

Mills will be back in court Wednesday for a bail hearing. The others are expected to appear in court on Thursday.

The RNC said it is actively continuing this investigation.
