Detectives hunting the Omagh bombers know who was responsible but have not been able to charge them, the head of the inquiry team said today.
At least six people, including one from Omagh, are suspected of involvement in the August 15th atrocity which killed 29 and left hundreds injured, Detective Chief Supt Eric Anderson said.
Members of the "Real IRA" in Armagh, Monaghan and Louth are believed to have planned the attack but although police have drawn up a list of suspects they are still trying to build a case strong enough to convict them. "We have a fair idea who did it; we probably know about half a dozen who were involved," Mr Anderson said. "We are trying to work out their actual roles. The problem is producing a case that convicts them. It's one thing to know who did it and another to produce evidence to put them away."
Up to 20 people have been questioned about the bombing but all were released without charge. Mr Anderson has said he believes some of those detained in the police operation on both sides of the Border were responsible.
"It's a long, protracted process involving many avenues of investigation and we're not there yet," he said.
