“Myself and another neighbour went over to check what was going on,” she said.
“We tried to get into the house but all the curtains were shut and doors closed, we had no idea if the kids were in there.
“I called Fire and Emergency because no one else seemed to react.”
The woman said the alarm kept going off and she became concerned.
“It’s just awful, those kids are just babies, you don’t leave your kids alone at home, you just don’t do it,” she said.
Fire and Emergency communications shift manager Blair Walklin said crews noticed “a smell of burnt cooking on arrival”.
“We found unattended cooking inside the house.”
Police thanked neighbours of the property who called for help and prevented a tragic outcome.
A 35-year-old woman was taken into custody on Wednesday morning.
She’s facing charges for ill-treatment of a child, resisting police, and possession of a cannabis plant.
She is due to appear in Christchurch District Court on July 31.
