The Inspector-General of Police (IGP), Usman Alkali Baba, has ordered the suspension of issuance of police permits to owners of vehicles with tinted glass.
He also ordered the suspension of issuance of spy number plates across the country.
The IGP gave the directive at a meeting with top police officers at the Nigeria Police Force headquarters in Abuja on Monday.
The measures are reportedly part of efforts being put in place to curb the worsening security challenges across the country.
