Suffolk police say candy received from trick-or-treating was found with a blade inside of it.

A 13-year-old girl was trick-or-treating on Halloween and traded candy with her classmates at P.J. Gelinas Junior High School over the past few days. The girl found a blade in a mini 3 Musketeers bar on Thursday.

The student's mother reported it to police at around 7:30 p.m.

Police are asking residents to make sure adults are present when children open candy they received on Halloween, especially in Stony Brook and Setauket.

Officers are asking anyone with information to call the Sixth Precinct Crime Section at 631-854-8626 or anonymously to Crime Stoppers at 1-800-220-TIPS.
