In what is thought to be the first case of its kind, Jacob Ladley (pictured) took to social media after three schoolgirls were murdered by Axel Rudakubana, then 17, in July last year.
The 18-year-old is seen in dashcam video from a taxi calmly walking through an open door into Southport's Hart Space building before slowly climbing the first few steps.
The terrified local can be heard shouting these remarks to police outside the Hart Space building in Southport after Axel Rudakubana had killed three children in July last year.
Speaking publicly for the first time since the massacre Leanne Lucas described helping young girls flee to safety and calling 999 as child killer Axel Rudakubana chased after them.
Retailers will now be required to report any suspicious bulk purchases of knives to the police, while the penalty for selling bladed weapons to under-18s will rise from six months to two years.
