A teenager has been charged with murder in relation to a 16-year-old dying in hospital after an assault at the Bus Hub in Dunedin on Thursday.
Police said the assault on Great King St was reported just after 3pm. Dunedin Central Police Station is on the same street.
Police are still working to establish the circumstances leading to the assault but confirmed on Friday they recovered a knife from the scene.
The victim was transported to Dunedin Hospital in a serious condition and died a short time later.
Otago Coastal Area Commander Inspector Marty Gray said the scene examination on Great King Street is now complete and several enquiries are underway.
A post-mortem is expected to be carried out on Friday and next-of-kin notifications are ongoing.
"We are working, along with Victim Support, to support the victim's family at this extremely difficult time," Inspector Gray said.
"We continue to ask anyone who witnessed the incident or took photos or video footage to get in touch with Dunedin Police via 105, quoting file number 240523/3321."
He noted the incident has been "extremely distressing" for the community, and police are patrolling the area.
"Police have been aware of anti-social behaviour at the Bus Hub for some time and have been working closely with the Dunedin City Council, Otago Regional Council and other partners to address this issue," Inspector Gray said.
"There has been extra CCTV put in place, as well as security staff patrolling the area. Security was working at the Bus Hub yesterday when this incident occurred and quickly intervened when they saw the altercation.
"Police have increased our foot and car patrols in the area focussing on peak times to ensure high visibility of police officers.
"As this matter is now before the courts, we are unable to comment further but we can assure our community that we have been working hard, along with our partners to address the issues, particularly involving youth at the Bus Hub. The incident yesterday was a tragedy, and our hearts go out to the victim and his family."
The teenager will appear in the Dunedin Youth Court on Friday.
