It also said police and public utility officers account for more than half of the bribes received in the country in the year.
The report entitled, ‘Corruption in Nigeria: Patterns and Trends’ was launched on Friday in Abuja.
Speaking at the event, Oliver Stolpe, country representative of the UNODC in Nigeria, said the drop in the prevalence of corruption in the country was as a result of measures undertaken by the federal government in the last three years.
“Most encouraging, the situation as concerns the agencies of the criminal justice system or institutions that form the criminal justice system as well as specialised law enforcement agencies we saw a drop in the prevalence of corruption,” Stolpe said.
“So contact with the police officers as regards the context for bribe dropped from 46 percent in 2016 to 33 percent in 2019. Prosecutors dropped from 33 percent to 21 percent. Judges from 31 percent to 20 percent.
“You can see a relatively dramatic drop here which is really a good sign on the terms of the measures that have been taken in the last three years.
“It is actually interesting to see that of all the bribes that have been paid, only very few agencies are responsible for their collection. There are two types of public official that account for more than half of the bribes that are being collected. Seven agencies are responsible essentially of 80 percent of all the bribes.
“There are the police and public utility officers – together are responsible for more than half the bribes.”
According to him, Nigerians pay for bribes to speed up a process or avoid paying fines.
