Westminster Muslim terrorist Khalid Masood took steroids and pledged allegiance to ISIS on WhatsApp, before he mowed down four pedestrians and stabbed a police officer in the horrific terror attack.
Masood, 52, was shot and eliminated by police after he drove a rental car into pedestrians on Westminster Bridge before fatally stabbing PC Keith Palmer, 48.
The Muslim terrorist, who was born in Kent, may have taken performance enhancing drugs hours before he launched the terror attack on Westminster Bridge, a pre-hearing inquest at the Old Bailey was told.
Evidence of rage-inducing substances were found in a urine sample taken from Masood’s carcass after the terror attack.
The families of his victims today called for internet giants to police terrorist material online and questioned why apps like WhatsApp and Telegram require end-to-end encryption.
They also asked that upcoming inquests into the terror attack to investigate whether Masood, 52, was radicalized online or in prison.
Gareth Patterson, QC, representing the victims, said: ‘Why it is that radicalization material continues to be freely available on the internet we don’t understand.
‘This particular attacker used WhatsApp to send a jihadi document without any difficulty.
‘We just don’t understand why it is necessary for WhatsApp and Telegram and these sort of media applications to have end-to-end encryption.’
