A teen who murdered two sisters to make a pact with a demon will be "a killing machine" when he leaves prison, the mother of his victims believes.

Evil Danyal Hussein brutally attacked Bibaa Henry and Nicole Smallman in Fryent Country Park in Wembley, north London, last summer.

When the vile 19-year-old was arrested, police discovered he had made a pact with a mythical demon to kill half a dozen women every six months in return for winning the lottery.

The murderous youngster was convicted at the Old Bailey on Tuesday but it has since emerged jurors were not told he had been monitored by police amid fears he was vulnerable to violent extremism.

Bibaa and Nicole's mum, Ramsgate's Mina Smallman, told BBC News: "The problem is the people who are supposed to be assessing and taking responsibility, there’s a gap from stage to stage so they get lost in the system.

“The saddest thing is, if this young man does have this tendency, when he goes into prison he is going to be even more radicalised.

“He is a killer now, he’ll be a killing machine by the time he comes out.”

Hussein had been on a de-radicalisation programme between October 2017 and May 2018 after being referred to the Prevent scheme by his school.

And last year, detectives also found he had communicated with others about demons and love potions, while also carrying out research online about the far-right and Norse mythology.

Mrs Smallman, a retired Church of England cleric, says authorities should be allowed access to all communications devices belonging to those suspected of extremism.

“Once they have proven they are not working within the right systems, they’re not in a good place, we need to be able to gain access to that information,” she added.

Hussein will be sentenced on September 22.
