Reading attack: suspect ruled out as possible terrorist twice in two years

Both Prevent and MI5 deemed Khairi Saadallah not worth investigation, while police still seek motive for triple stabbing

The suspect in the Reading stabbings was twice assessed by security services but was deemed to pose no danger of staging an attack, it has emerged.

Khairi Saadallah, 25, was referred to Prevent, the government’s anti-radicalisation strategy, and then to MI5 in the past two years. He was arrested on Saturday following the stabbing to death of three men in a park in Reading, Berkshire.
