PC Chessor told the jury that Albadri had made a hand gesture “like a salute” just before he jumped onto the railing.
On police body-worn video footage Albadri can be heard saying: “I’m gonna come again.”
When PC Cox asks him: “Have you got anything on you that’s gonna poke me?”, Albadri replies: “I got my weapons.”
The court was told that officers discovered two small knives with red-and-white handles in his pockets.
Albadri says: “I wanna make a crime inside there. Why are you stopping me? Why are you stopping me from making crimes?”
Later he adds: “Why didn’t you let me in?”
Albadri’s lawyer said he then added “and then do what you want to do”.
He is also heard to swear and say “they need to stop” the “war on children”.
Earlier the same afternoon, the jury heard, Albadri had WhatsApped his mother a picture of a handwritten note next to a knife with a red-and-white handle.
The note ends with the message: “I will not go back on my decision to go in the cause of Allah, to come out for His sake and to stand up to the enemies in order to support the religion of Allah Almighty.”
In a subsequent message to his mother, he wrote: “I chose the path of martyrdom”.
The handwritten note was found on him at the time of his arrest, the jury heard.
The trial continues.
