Haisam Nassir, 25, said her “anxiety went off the roof” after finding 450g of crystal meth inside the Golden Morn breakfast cereal, and is thankful her children did not consume any

A mum-of-four who found almost half a kilo of crystal meth inside her kid’s cereal box has said her “anxiety went off the roof” after making the shocking find.

Haisam Nassir, 25, was dishing out breakfast to her four children aged three, two and one-year-old twins, in the summer when she realised something was wrong.

She was trying to pour more of the Golden Morn cereal, and despite feeling it was still half full, no more crunchy maize flakes were coming out.

When Haisam put her hand inside she could feel an extra bag blocking the rest of the cereal.

After pulling the bag out, she could see it was filled with white crystals, and after some research was shocked to discover she was handling methamphetamine, a class A drug.

Better known as crystal meth, the substance is known to be highly addictive – and featured heavily in the hit show ‘Breaking Bad’.

Worried Haisam, from Dagenham, Essex, took the bag to the police, who later confirmed her fears.

She also rushed her children to hospital in case they had eaten any of the class A drug, but doctors said they had not been affected.

Stay-at-home-mum Haisam said: “It was so so bad, I was really shocked. It was massive – it took up nearly half the box.

“I felt really frightened. My anxiety went off the roof. There was 450g of it. The street value would be quite something.

“Imagine if that burst it could have had a deadly impact. It could have ended so badly.

“They’d been eating from that box for four days straight and the bag of crystal meth was really thin, a sharp piece of cereal could easily have made a hole in it.

“My eldest is very independent and gets her own cereal. She could so easily have eaten it.

“I was having these heartbreaking thoughts. I could have gone from being a mum of four to a mum of none very quickly.”

Haisam said officers at her local police station were shocked to see the massive bag and the kids were checked out at Queen’s Hospital.

She said: “It was an horrific experience. I still can’t believe it was in my house with my kids.”

“I bought [the box] at my local shop, five minutes away from me.

“It’s an international shop, quite similar to a corner shop, [with] loads of world foods from other places such as Pakistan.

“It’s probably imported, only specific shops have this cereal.

“I have been getting the cereal from that specific shop regularly for like six months.

“Normally I go in and get two bags. I did that this time too. The first bag I bought was fine.”

A police investigation into the June incident found a cut in the bottom of the cereal bag, through which they concluded the drug bag had been inserted.

A formal letter sent to Haisam said: “It appears highly unlikely that the crystals were inserted at the factory of production, though this cannot be established for certain.”

The letter also explained that a man had been arrested on suspicion of drugs offences but was later released under investigation.

And the case is closed for now – which has left Haisam unhappy.

“I can’t believe the case has closed. It’s really shocking,” she said. “I feel like no one is taking it seriously. It makes no sense.

“My children could have consumed it – and there could have been a very different outcome.”

A Nestle spokesperson said: “This case was investigated six months ago by both Nestl and the police.

“It was concluded that the item was inserted into the packaging at some point after the product left Nestl in Nigeria.

“This is not a product we manufacture or distribute in the UK, but we appreciate how concerning it must have been for Haisam and worked closely with her to resolve the issue since she first contacted us in June.”

The Metropolitan Police have been approached for comment.
