Police are investigating after a three-year-old boy found a bag of syringes while playing in a Toronto schoolyard.

According to the Canadian Press, the toddler scratched his hand during the incident Saturday evening.

Police are investigating what was in the syringe.

In September, a similar incident occurred when a 15-month-old child found prescription pills in a park. The child’s mother had to take the pill out of the toddler’s mouth.
