Canterbury Police were alerted to a domestic incident at a Tinwald address at around 3.45pm this afternoon (18 October 2015).
Sergeant Richard Scott says no one was injured but a car at the address has been damaged and the occupants threatened with a knife before a man fled the scene on foot.
"The knife has not been located and we ask the residents of Johnstone Street to check their front gardens and contact Police straight away if they find one on their property. Please do not pick it up."
Police would also like to hear from anyone who witnessed a man wearing dark clothing with a youth aged around 14 years running along Thompson Street at around 3.45pm this afternoon.
"The pair are then understood to have continued along Johnstone Street, over State Highway one to the corner of Compton Street and George Street in Tinwald this afternoon" explains Sergeant Scott.
A 24 year old man has been arrested and is due to appear in Ashburton District Court on Monday 19 October 2015 charged with possession of an offensive weapon, threatening to kill, aggravated burglary, breach of protection order and wilful damage.
Anyone who saw the man and youth or finds a knife on their property should contact Ashburton Police Station on 03 3078400.
