An evacuation of an Invercargill street was caused by a person using cannabis oil.

Police and fire services evacuated nearby residents of Tyne St as a precaution when they received reports of a strong chemical smell at The Haven about 2.15pm.

Cordons were put in place and additional staff were sent to safely remove children from the nearby school, but the fire service has now confirmed the smell came from somebody using cannabis oil.

Police officers in the area are still looking for the alleged offender but cordons have now been taken down.
