A woman convicted of deliberately poisoning four young children in her care has been released from prison and will be living in Brampton, Peel police are warning.

Police said Christine Allen, 36, was to be released on parole Monday, July 24 and is at an “elevated risk” to reoffend, says Correctional Service Canada.

A Kitchener resident at the time of the crimes, she was released after serving a six-year sentence. Allen was convicted of four counts of administering a noxious substance to cause bodily harm in 2014. She deliberately poisoned four young children in her care. All four fell ill, and one suffered “serious harm,” said police.

Peel police issued a public safety advisory, warning about Allen’s release and decision to live in Brampton.
