Early last year, it received a complaint that Creelman had been operating a security business without holding the appropriate licence.
An investigation also established that Creelman had engaged at least two people to work in security who did not hold the required approval certificates.
In August, she was warned that she needed to stop trading until she got the correct licences.
Creelman gave an undertaking that she would take steps to remedy the breach.
The authority said she accepted she had never applied for or held an individual security licence and that Dubble H Security Limited had not applied for a company licence.
She was sent a copy of the investigation report with a notice of hearing, and while she indicated she planned to attend via audio link, she did not show up.
The licensing authority considered it was appropriate to refer the complaint against Creelman back to the Complaints Investigation and Prosecution Unit for further investigation and possible prosecution.
Because Creelman was found guilty of misconduct, and that it was ongoing, the Authority’s Patricia McConnell was satisfied that she was no longer suitable to be a certificate holder.
“I also note that Ms Creelman has continued to wrongly use her COA as justification for running a security business.
“I therefore conclude it is appropriate to suspend Ms Creelman’s certificate of approval pending the completion of the further investigation and any future prosecution,” McConnell said.
