Abuse of the naira.

The Central Bank of Nigeria (CBN) considers abuse of the naira a serious offense, as it can lead to a shortage of currency in circulation, increased costs for printing and replacing damaged notes, and a loss of confidence in the currency.
The CBN has implemented measures to prevent the abuse of the naira, including:
In April 2024, a prominent Nigerian cross-dresser, Bobrisky, was arrested for defacing naira banknotes. The arrest was made by the Economic and Financial Crimes Commission (EFCC) after an investigation into social media videos that appeared to show Bobrisky throwing money in the air at a film premiere the previous month. Bobrisky entered a guilty plea to four counts of currency abuse on April 5, 2024, and was sentenced to six months in prison with no option of fine on April 12, 2024.
