BOBBY Storey's cremation at Roselawn Cemetery was attended by 28 mourners and council wardens rather than republicans manned the gates.
An internal report by Belfast City Council also found there were "no paramilitary trappings, guard of honour or flag" at the ceremony.
The veteran republican was cremated at Roselawn on June 30.
There has been concern raised about attendance and why some staff had been sent home early.
The council already apologised and offered compensation to eight other families who were not allowed to attend services on the same day.
According to the report, council Chief Executive Suzanne Wylie received two phone calls from Sinn Féin about the numbers who could attend.
A decision by Nigel Grimshaw, the council's director of city and neighbourhood services, to allow up to 30 mourners, was taken "in the context of managing potential issues if numbers arrived and demands for access were made".
Mr Grimshaw confirmed that he would send up to five stewards to Roselawn to assist with identifying family members and mourners.
The report said: "There have been no reports of intimidation or harassment of staff. To the contrary I am advised by council officers that the occasion was respectful. There were no paramilitary trappings, guard of honour or flag. Council officers described the occasion as a ‘low key dignified send off'.
"The gates of Roselawn were controlled by council wardens at all times. There is nothing in the CCTV footage that provides any evidence that Roselawn was under control of persons other than council officials."
The report stated that 28 mourners were present at the service.
"This is taken from a head count carried out by a member of staff which tallies with the estimate made by a warden that the number of mourners was in the high twenties. One individual, identified by staff as a ‘local’ was observed riding his bicycle close by. There is no evidence of others present or people having entered, other than the individual referred to, by alternate means.
"The family used their allocated 30 minutes (families are allocated 15 minutes for the outdoor service but operationally we allow 30 minutes for the whole process for each family). This suggests that the service was conducted promptly and that mourners did not remain on the site following the committal.
"Three slots were held after the cremation of Mr Storey. In order to accommodate the sensitive nature of cremation services and burials that day, and in tandem with protecting the privacy of families, this sort of arrangement is not unusual as a precaution to ensure mourners arrive and leave without the individual parties being on-site at the same time. The cancellation of other cremations did not occur. Roselawn was at that time operating under capacity. Four cremations out of a total possible number of 16 took place on 1 July."
It added that some staff were sent home early saying this was an operational decision.
"The decision was motivated by concerns that more people than permitted may attempt to gain access at the site and to avoid staff being photographed or feeling uncomfortable and to prevent any potential issues arising in the car park area where some temporary staff accommodation was situated. 15 staff remained on site. The director of city and neighbourhood services was consulted on the decision to send staff home insofar as it related to maintenance and grave digging staff. There were no more burials planned that afternoon."
