A 19-year-old man was expected in court after an alleged firearms incident in Christchurch on Christmas Day.

The man was charged with wounding with intent to cause grievous bodily harm, after a person was found with a suspected gunshot wound, Detective Sergeant Luke Vaughan said today.

Det Sgt Vaughan said police received multiple calls shortly after 6.30pm, reporting a man being chased on Amyes Rd in the suburb of Hornby by others, including one carrying a firearm.

Several vehicles in the area fled the scene.

Police went to hospital and found one person with a suspected gunshot wound which was not considered life-threatening, Det Sgt Vaughan said.

Officers spoke to several people at the hospital, and further inquiries led police to another location of interest.

A 19-year-old man was arrested at an Amyes Rd property last night and would appear in Christchurch District Court today.
