Role of Special Branch
Ombudsman's allegations
The ombudsman's report says that two days after the bomb, Special Branch officers provided the investigation team with "limited intelligence" on five suspects.
It attacks Special Branch for not subjecting the Kevin Fulton allegations to rigorous analysis.
The ombudsman said that 78% of the documents it found relevant to the inquiry had not been passed to the Omagh crime team and, furthermore, the department was "reluctant" to provide access to her team.
PSNI's rebuttal
Special Branch is "not a force within a force" working independently of the rest of the police service, the rebuttal says.
But it insists that it needs to have safeguards in place to protect sensitive information because lives depend upon it doing so.
Turning to the Kevin Fulton allegations, the PSNI says that Special Branch treated the information as it did any other of the 14,000 items of intelligence it received that year.
In this case, it says, the information proved irrelevant to the Omagh bombing.
