Police are investigating after a bag suspected of containing cocaine was found in a trick-or-treater's bag on Saturday night. 

According to a Facebook post from Ingram Borough Police, on Saturday night, they were alerted to an unknown substance in a child's trick-or-treat bag. 

When given the evidence, the powder was in a small, knotted bag, and preliminary tests came back positive for cocaine. 

"A grandmother had found a small baggie of cocaine, or we suspected cocaine at the time, in the 8-year-old's bag. We obtained it, we tested it, it came back positive on the test for cocaine derivative," said Ingram Police Chief Jack Doherty.

The police chief said it was the biggest night for trick or treating he had seen in his 25 years.

"I don't feel that this is nefarious. People that can afford that kind of drug aren't passing that kind of a drug out," said Ingram resident Shelley Johnson. 

"My hope is that it was an accidental occurrence, that someone wouldn't drop cocaine in a bag of candy for children. I hope that's a mistake," said resident Simone Freeman-Irwin.

Police are continuing to investigate, but they think it was probably a mistake. 

"I was just this morning at a couple of houses, I was talking to some people about it and no new information was obtained," Doherty said.

Doherty admitted not knowing where it came from is a challenge for the investigation, but from his experience, parents shouldn't be too concerned to take their kids trick or treating. 

"I don't think I would be overly concerned. But I certainly would check the contents of the kids' bags that they get," Doherty said.

"Yeah that's good advice anytime, even if this wasn't found," he added.
