Parents are being urged to check sweets collected by children whilst trick or treating on Halloween after parents reported suspicious chocolate in Swindon.

Reports surfaced on social media on Tuesday morning of alleged sweet-spiking incidents.

Images have been shared on Facebook of a number of sweets that appear to have been pierced with holes.

There are also reports that one girl spent a night in hospital after eating a spiked sweet.

Wiltshire Police said they have received two calls to concerns that arose after trick or treating on Monday.

But they said they "do not believe the sweets have been contaminated on either occasion".

Victoria Ann Munday, who lives in Walcot, revealed that she found a strange-looking chcolate among her five-year-old son's trick or treating stash, after he had been trick or treating in Walcot.

She told the Adver: “My son had been trick or treating in Walcot and he had some Quality Street sweets in his bag when he got home.

“The wrappers looked like they have been tampered with as they had holes in the sweets.

“It’s disgusting that there are people out there who can do this to kids, it’s just sick.

“Thankfully my son didn’t eat them, he’s only five. But if he had eaten them, it would have been a completely different story.”

She is now urging other parents to check their children’s sweets.

In a post on Facebook, she said two sweets were “not wrapped properly and both have holes in them”.

“Please also check your kids’ sweets,” she added.

A spokesperson for Wiltshire Police said: "We are aware of a number of posts on social media regarding concerns relating to sweets given out to children ‘trick or treating’ in the Walcot area last night.

"We have received two calls in relation to this and we do not believe the sweets have been contaminated on either occasion.

"We are advising parents who are concerned about any sweets collected by children this Halloween, to please discard of them immediately."
