Police are continuing to appeal for information regarding a white van used in the London Bridge terrorist attack
Detectives investigating the attack have established that the three pink knives used by the attackers were purchased from a specific shop in east London.
We thank the media for their assistance in publicising the appeal for information on the knives last week.
The Met’s Counter Terrorism Command continues to appeal for witnesses to the incident or anyone who saw the white Renault van, registration plate HN66 TKX - used by the attackers - on Saturday, 3 June to call police in confidence on 0800 789 321.
The attackers first drove southbound onto London Bridge at 21:58hrs. They drove off the bridge turned round and drove back, northbound up the bridge again. Once at the north end, the attackers did a U-turn and drove back southbound, fatally and purposely driving into pedestrians as they did so.
They then crashed into railings outside the Barrowboy and Banker pub. Here, the men abandoned the van and ran off to Borough Market where they began to stab members of the public.
Counter terrorism officers have so far spoken to 262 people from 19 different countries. Of these, 78 are significant witnesses.
Commander Dean Haydon, said: "Many witnesses we've spoken to have provided extremely helpful accounts of the attack but we are still missing pieces of the picture.
"My officers are particularly keen to hear from anyone who witnessed the white van targeting individuals on London Bridge, saw the suspects attacking members of the public or saw armed police engaging the suspects."
Security measures have been stepped up across London, with protective barriers being installed at eight bridges across London to maintain security at these venues.
Police are considering the use of barriers and other security measures at crowded and iconic locations across London and continue to review security at events over the summer.
They are also continuing to work with haulage and vehicle rental companies to develop a greater understanding of potential risks and suspicious activity they should look out for.
