A criminal investigation is underway after the sudden death of a one-year-old toddler in Strathroy on Wednesday.

Emergency crews reportedly responded to the home around 11 p.m., including police and ambulance, and later the coroner.

The Strathroy-Caradoc Police Service is continuing to investigate and police tape could still be seen outside the home at 355 Penny Lane on Thursday.

The OPP Criminal Investigation Branch and the OPP Forensic Identification Unit have also been called in to assist.

Neighbours say the family moved into the home just three weeks ago and that the toddler was a boy.

The investigation is ongoing and police say further details will be released when they are available.
