The officer leading an investigation into the killing of 14 people in Londonderry on Bloody Sunday says the response to his witness appeal on the 42nd anniversary has been disappointing.
Detective Chief Inspector Ian Harrison, said: “The response to our original appeal for witnesses to talk to us has been disappointing. If we are to make progress, we need witness statements.
“We are renewing our appeal and placing additional advertising to increase awareness of what we’re working to achieve.
“The adverts asking people to come forward will be in local newspapers and on billboards in Derry.
“We need people to work with us. If people don’t come forward, it will further delay this lengthy and complicated process.”
On January 30, the PSNI asked more than 1,000 witnesses, consisting of local people and former soldiers, to again make statements as part of the criminal investigation.
The PSNI says it is obliged to re-interview surviving witnesses because police are precluded from using the Saville Inquiry testimony in a criminal investigation.
Civilians and former soldiers are asked to contact the investigation team on 028 9025 9593 or by email to BloodySundayEnquiry@psni.pnn.police.uk
