A UK teenager on trial for the deaths of two sisters has been accused of killing them as a sacrifice to a demon so he could win the lottery.
Danyal Hussein, 19, is on trial for the murders of 46-year-old Bibaa Henry and 27-year-old Nicole Smallman on June 6 last year.
London's Central Criminal Court heard that Henry and Smallman had attended a birthday party in Wembley's Fryent Country Park, Sky News reported.
The sisters had decided to continue partying past 1am after their friends had retired for the night.
However, they couldn't be contacted the next day. During a search for the sisters, their bodies were found with multiple stab wounds near where the party was held, BBC reported.
Prosecutor Oliver Glasgow told the court the attack was "savage" and "devastating".
CCTV footage revealed Hussein, who was earlier seen buying knives, had entered the park on the night of the murders holding a mask and shovels.
Glasgow told the court on Wednesday (local time) police had found a strange document while searching Hussein's apartment.
"The police found a handwritten document, purporting to be an agreement between the defendant and a demon, in which he promised to sacrifice women in order to win the lottery and not to be suspected of the crimes he had committed," he said, according to Sky News.
"It would appear that the defendant had confidence that his plan would work since following the fatal attacks upon Bibaa Henry and Nicole Smallman, the defendant purchased several lottery tickets and there were three lottery tickets folded up inside the note.
"As it turned out, the demon did not come good on the bargain, since not only did the defendant not win the lottery but the police identified all the evidence that links him to these two murders."
Hussein has denied any involvement in the crimes and denies he wrote the note.
The trial continues.
