Paratroopers could be prosecuted over Bloody Sunday on evidence provided anonymously by fellow soldiers, it has emerged.
Nobody was ever convicted after 14 civilians were killed in the 1972 atrocity in Londonderry.
Now the senior officer leading the PSNI investigation has said criminal proceedings could be instigated against soldiers on the basis of accounts provided by unnamed witnesses of events.
The final decision, he said, would lie with the courts and could lead to soldiers standing trial for murder.
The PSNI has encouraged Paras and the public to come forward with information they have on Bloody Sunday.
Detective Chief Inspector Ian Harrison, writing in the regiment's official journal Pegasus, said: "During the Saville Inquiry it was ruled that anonymity was granted to any former soldier who gave evidence unless his name was clearly already in the public domain.
"That ruling does not automatically carry over to the current police investigation. Anonymity will be a matter for a future court to consider."
