Rabby Pramudatama, Jakarta – A police watchdog wants the police to investigate Democratic Party chairman Anas Urbaningrum for allegedly using unauthorized license plates on two of his cars.

"I think the police should take this case to court in order to educate people on traffic law enforcement," Johnson Panjaitan from the Indonesian Police Watch (IPW) told reporters on Wednesday.

Johnson said the police have not launched a criminal investigation of Anas since the story was only broadcast by the media and that officers did not personally observe the license plates.

Using cunauthorized license plates, Johnson said, was a "very serious" offense and no exceptions could be made in enforcing the law.

Anas and his wife, Athiyyah Laila, were seen driving a Toyota Innov with a license plate bearing B1716 SDC to the Corruption Eradication Commission last week.

A media report noted that the same license plate number was observed on Anas' Toyota Alphard Vellfire when he attended a Democratic Party event in Cibubur, East Jakarta, in early March.

According to the police, the B1716 SDC license plate was assigned to neither of the vehicles. The Jakarta Police have declined to confirm if Anas or his driver would be liable for using the allegedly unauthorized plates.
