9 Usman Khan was wielding two knives when he was eventually pinned down on London Bridge on Friday

And he would laugh and enjoy continually watching footage of the 9/11 attack on his mobile.

A former pupil at what was then called Haywood High School told The Sun he would ask girls the size of their boobs, ogle at them, wolf whistle and try to touch them.

When he was turned down he would intimidate them and brand them “sl*ts” and “w***es”.

The former pupil, who did not want to be named, told The Sun: “He had a picture of Osama bin Laden on the front of his school planner.

“It was like an A5 picture he had stuck on there. We were all disgusted by it. It was awful.

“He would also watch the videos of 9/11 in the lunch hall. We could see him looking at them. Nobody was comfortable.”

Khan left the school aged around 16 in 2007.

“Quite a few people reported it. When they did they were brought into an office (at the school) and the whole racism thing was laid down to them.”

On Friday he then carried out his horrific attack, stabbing two people to death while wearing a fake suicide jacket. He then made his way to London Bridge where cops shot him dead.

The former pupil said she was “stunned” to discover he was responsible.
