Eight people died in the attack on June 3rd
London Police are seeking the assistance of Irish people who may have information about the terrorist attack at London Bridge last week.
Officers are particularly keen to hear from anyone who witnessed the white van targeting individuals, saw the suspects attacking members of the public or armed police engaging the suspects.
Anyone who may have information about the incident, or saw anything, is asked to make contact with the counter terrorism police in London via this website.
The appeal was made in a statement from An Garda Síochána on behalf of the London Metropolitan Police.
A van mounted the pavement on London Bridge on June 3rd, killing three people.
Three men crashed the vehicle into railings and then ran through Borough Market, randomly stabbing people at bars and restaurants.
Armed officers arrived and shot the suspected attackers dead.
Eight people died in the attack, including one man who was pulled from the River Thames.
It has since been revealed that the attackers tried to hire a 7.5-tonne lorry online on the morning of the attack.
Police also discovered Molotov cocktails inside the van that was used. It is thought these could have been intended for another wave of attacks.
Police Commander Dean Haydon, head of Scotland Yard's Counter Terrorism Command, said: "We've been working round the clock to understand what these men did in the lead up to the attack, but we need to know more about these unusual knives.
"Where have they come from? Where might the attackers have bought them? If you know anything about these particular types of knives, please let us know. It could prove a crucial lead in our investigation."
