Attacker's digital footprint will be crucial for investigationpublished at 05:48 BST 3 October

One of the highest priorities for the investigators is identifying everyone whom the attacker was in contact with, prior to his being shot dead at the scene.
Jihad Al-Shamie is not thought to have been the subject of any ongoing current investigation.
But that does not mean his name won’t crop up in connection with other investigations by Counter Terrorism Policing or the Security Service, MI5.
Experts say it is rare for a perpetrator to be acting in complete isolation.
Analysts at JTAC, the Joint Terrorism Analysis Centre in London, have been working flat out to determine whether they need to raise the National Terrorism Threat Level from its current level of "Substantial" to the next rung up, "Severe".
It’s been at "Substantial" since early 2022, meaning a terror attack is thought to be "likely".
Much will depend on what clues can now be gleaned from Al-Shamie’s digital footprint, such as the numbers stored in his phone and his activity online.
This investigation is still in its early stages.
