TWISTED killer Danyal Hussein believed he had struck a deal with the devil when he stabbed two sisters to death in a park.

       The deluded 19-year-old Satanist, who was today jailed for life for the double murder, was convinced his "sacrifice" would see him bag the Mega Millions Super Jackpot lottery prize of ￡321million.

       But hints at his future "campaign of vengeance" started long before the "frenzied" attack on Bibaa Henry and Nicole Smallman.

       Hussein was reportedly "very mischievous" as a schoolkid in south east London and was constantly in "a lot of trouble".

       But it wasn't until the age of 15 that the alarm was really raised and he was referred to an anti-terror programme after being caught viewing dead bodies on his school computer.

       The student was passed to the Home Office Prevent scheme by teachers over concerns he was vulnerable to jihadist radicalisation.

       No hint of Islamic extremism was found - until his arrest for the murders of Bibaa and Nicole.

       His "savage" knifing of the sisters was part of a pact he had made with a demonic entity called King Lucifuge Rofocale, which was signed in blood.

       In exchange for killing six women every three months, Hussein would become a millionaire after winning the lottery, it said.

       The agreement was found next to three lottery tickets, and bank records later showed several bets were placed on June 7 last year, the day after the killings.

       In the days that followed, Hussein went on to buy further tickets, all unsuccessful.

       But even before he carried out his sick attack, the teen had communicated with others about demons and love potions, and carried out online research about the far-right and Norse mythology.

       It is believed he was influenced by the work of an American black magician who has links with a British-based Nazi Satanist group known as the Order of Nine Angles.

       Facebook has since removed his page and Instagram account, and YouTube launched a review.

       As well as the pact with the devil, police found "disturbing" notes in Hussein's bedroom which offered blood in exchange for making a woman fall "deeply in love" with him.

       One was addressed to Queen Byleth and was discovered in a pouch containing a pendant and other papers.

       Following his arrest, Hussein refused to give police access to his laptop and iPad, which he had frequently used to access the dark web.

       Both were protected by encrypted passwords in an "almost move-like" way, police said.

       'SAVAGE ATTACK'

       Hussein, who comes from an Iraqi Kurdish background and is the eldest of four children by his divorced parents, was eventually found guilty of murder.

       While in court, he sparked outrage by trying to catch the attention of his victims' family, making L-shaped loser signs to a paramedic witness and turning his back on the judge.

       Detective Chief Inspector Simon Harding said: “He showed disrespect for everything, for the families, support systems, the process, police, paramedics, everybody - and the jury."

       The court heard how on the night of the killings, Hussein armed himself with knives, shovels and wore a mask and surgical gloves before entering the park with a rucksack on his back.

       He is thought to have kept watch on the sisters after they remained behind alone after their birthday celebrations.

       Prosecutor Oliver Glasgow, QC, said the attack on the sisters was "as savage as it was devastating."

       Bibaa was stabbed eight times with no marks to her arms and hands suggesting she did not have time to defend herself.

       Nicole was stabbed 28 times and sustained cuts to her hands, arms and legs as she tried to fight back.

       If he hadn't been caught, four other families may have been suffering what we have.

       Mina Smallman

       After the brutal stabbings, Hussein dragged both bodies about 75 yards into some trees, leaving his and their blood all over the picnic site.

       He then went home and woke his dad up to let him into the house.

       Nicole’s boyfriend Adam Stone reported the sisters missing, and later found their bodies intertwined.

       During his arrest, the cold killer stared at his own bloody hands but remained silent.

       He declined to give evidence in his trial and continued to deny being involved in the grisly murder.

       But on October 28, Hussein was sentenced to life behind bars, with a minimum of 35 years.

       'DELUDED HUMAN BEING'

       Sentencing him at the Old Bailey today, Mrs Justice Whipple said: "He has chosen his course and the consequences must follow."

       Following Hussein's conviction in July, the sisters' mother, the Venerable Mina Smallman, said she had "never come across such evil".

       And outside court today she blasted their "deluded" killer as a "broken human being" who could well have killed again following his "savage" attack on her daughters.

       "There's nothing wrong with Hussein, he is just an obnoxious human being," she said.

       "We don't need to see him. He is a broken human being.

       "If he hadn't been caught, four other families may have been suffering what we have. Well he ain't out there now."

       She then described the sentence as "justice for her beautiful girls", adding: "He is so deluded.

       "Come 35 years time, they won't let him out. I won't let them let him out."
