Halton police are alerting in a Milton neighbourhood about a potential-dangerous substance found in a child’s Halloween trick-or-treat bag last night (Monday).

Upon inspecting her 12-year-old daughter’s bag of candy, a mother discovered a mini rum bottle containing a clear fluid.

The seal on the bottle had been compromised and was leaking slightly when it was turned over to police. Officers were not certain if the liquid was indeed alcohol.

The bottle and liquid were sealed after an initial inspection and will be sent away for analysis to ID what it is.

Police have determined that the bottle was placed in the bag by a resident in the area of Childs Drive and Ledwith Drive. Parents of children who visited this area are urged to thoroughly inspect the candy.
