The Police is investigating the illegal use of registration number plates only meant for State House vehicles.

In a press statement published in the media yesterday, State House released a list of 168 number plates used on cars that are no longer under its ownership.

The deputy presidential press secretary, Linda Nabusayi, yesterday said some of the vehicles were boarded off in the late 1990s but the number plates were never returned.

"Some of the vehicles were taken over by the Ministry of Works and other agencies and they were required to return the number plates," Nabusayi said.

She disclosed that some people were using the number plates to commit crime and evade taxes, claiming to be State House officials.

In August, a Toyota Ipsum bearing State House number plate UG 0267C was used by a gang during a robbery in Ntinda, a Kampala suburb.

Nabusayi said State House is not responsible for the use and misuse of the said number plates.
