MET Police chief Cressida Dick has praised The Sun for its Amazon bomb-making exclusive.
Talking to LBC the top cop said she wanted to "thank The Sun" for its exposé which saw ingredients used to make a jihadi bomb bought in a single order without it being flagged to security.
Earlier today it was revealed Parsons Green Tube suspect Ahmed Hassan, 18, had bought some of the ingredients from Amazon to make the the 'Mother of Satan' bomb which failed to detonate last Friday.
Thirty people were injured including a schoolboy after a "fireball flew down a carriage" on the Tube train.
Speaking to radio host Nick Ferrari Dick said: "Thank you to The Sun because they didn't actually put in all the ingredients in their article.
"One of the things that has come to light recently [sic] is that people could request one particular item and then a whole load of other things which could be used to make a bomb would come together at once.
"Of course some of the materials are every day materials and we cannot restrict their sale. But a click-thru is ridiculous."
Current loopholes in government guidelines exposed by The Sun mean Amazon is technically free to sell and deliver the DIY bomb kits.
The Met chief continued to talk to Ferrari and LBC listeners on the difficulties police faced when tackling people who bomb-making ingredients online.
"We are constantly working with the Government on things that can be regulated properly are properly regulated and secondly that we have better and better methods of trying to understand and work with companies on this.
"When someone is doing something that doesn't seem right in terms of buying lots of hydrogen peroxide we would like to be alerted to that."
Yesterday The Sun revealed how ingredients which could make an IED like the one that killed 22 people at the Manchester Arena, could be purchased on Amazon in a single order for £95.
The Sun used an account on Amazon to buy items flagged on government warning lists.
One item, hydrogen peroxide, is restricted for sale by the Home Office but was readily available for a repeat order on the site.
A spokesman for Amazon said: “We only sell products that comply with UK laws.
“In light of recent events, we are reviewing our website to ensure these products are presented in an appropriate manner."
