The Transport Agency has reopened an investigation into how a senior manager oversaw the awarding of a contract to a company run by a close friend.
An inquiry found that contract was unfairly awarded.
It has also revealed that the manager, Martin McMullan, was accused of blocking competition for a technology contract.
Shortly afterwards Mr McMullan was promoted to one of agency's topmost jobs paying upwards of $150,000 a year. Phil Pennington is looking into this.
