London Underground bomber reportedly bought his key Ingredients on Amazon. Prosecutors say the terror suspect who planted an improvised bomb on a London Underground train bought the main ingredients for his homemade bomb from Amazon. Ahmed Hassan, 18, of Surrey stood before a judge for the first time on Friday since the botched bombing on the London Tube train carriage. He is now facing attempted murder charges. According to prosecutors, Hassan originally hailed from Iraq and was arrested at a port while trying to leave the country.

"Frequently bought together" on Amazon

Investigations have shown that Hassan used the chemical TATP, or triacetone triperoxide, and other ingredients in his improvised explosive device, which he placed in a plastic bucket inside a grocery store bag on the train. As reported by the Telegraph, while prosecutors say it is unclear where the bomber got all the materials involved in making the explosive device, they have established that the “key ingredients” were purchased from Amazon.

The online retailer came under fire recently after it was discovered that if customers looked at certain bomb-related items, including thermite and black powder, on Amazon, the website automatically directed them to other potential weapon-making materials under the popular “frequently bought together” tab that appears on Amazon’s pages.

According to a report by Channel 4 earlier this week, other potential bomb ingredients like steel ball bearings, used as shrapnel in homemade bombs, as well as other items such as remote detonators and ignition systems, are easy to purchase on Amazon. Their report states that these items are also promoted by Amazon under the heading “Customers who bought this item also bought.”

Channel 4 also reported that while searching for a particular chemical compound, commonly used in food production, the website also offered suggestions of other ingredients to make explosive black powder.

However, the website chose not to name that compound.

Amazon is now checking its algorithm

Amazon is now looking into the algorithm that comes up with the suggestions on their website. The company said in a statement that all the products sold on Amazon have to adhere to their selling guidelines and that the company only sells products that do comply with the UK.

laws. While not directly mentioning the current situation relating to the bomb-making materials purchased by Hassan, Amazon went on to say they are now running a review to ensure all the products in question are presented appropriately.

Hassan is the first of the three suspects to be charged relating to the Parsons Green bombing, which happened in the London Underground on Friday last week. According to the London Metropolitan Police, two other suspects are still in custody, while three were released without charge on Thursday.

Other news that emerged from the court hearing was that Hassan had left the train at one stop before Parsons Green, where the bomb exploded. Among the items used in the bomb were a variety of metal shrapnel ingredients, including screws, knives and other similar items, aimed at causing severe injuries.
