Police are urging anyone with photos, videos or dash-cam footage of the Manchester Arena explosion to hand them over to authorities “as a matter of urgency”.
Officers confirmed that the attacker was killed during the incident, with so-called Islamic State taking responsibility for the bombing.
Now Greater Manchester Police are asking concert-goers to help the investigation into the horrific terror incident by submitting any images or videos they have of the blast to the police image appeal website.
They are also calling on anyone who was in Manchester city centre last night between 8pm and 11pm to send their dash-cam footage to police as soon as possible.
Speaking earlier today, Chief Constable Ian Hopkins said: “Terrorists attempt to disrupt our lives and create distrust and fear in communities.
“We have a long history in Greater Manchester of communities standing together during difficult times. In the coming days we will be working closely with community leaders to address any issues.
“It is important that we all continue to remain vigilant, but also to go about our daily lives,” he added.
According to the police website, a police officer or professional staff member will “review images you upload to us as quickly as possible”.
Theresa May condemned the “sickening cowardice” of the suicide bombing, while people across the country donated more than £280,000 in a matter of hours to support the families of those killed.
