Police, on Sunday, seized the luxurious Cadillac Escalade sports utility vehicle (SUV) bearing registration number Dhaka Metro Gha-11-9999.

Sub-Inspector AKM Monjurul Haq Akon filed the case with Dhanmondi police station (PS).

"We're examining relevant papers of the automobile and have primary evidence that the registration number is a fake. Both the police and joint forces are investigating the matter," said a police officer.

Talking about the registration number, the officer told The Daily Star, "Bangladesh Road Transport Authority (BRTA) did not issue the number."

The officer-in-charge (OC) of Dhanmondi PS said Nazmul Huda did not seek a registration number for his SUV from BRTA, and put a fake number plate on the vehicle instead.

"It's a fraud case under article 420," the OC said.

Nazmul Huda's family however claimed that the luxurious SUV must have a genuine registration.

"It's funny to know that former communications minister Nazmul Huda would use an automobile without registration", a member of the Huda family told The Daily Star.

Huda submitted all the relevant papers of the vehicle including its registration papers, the family member claimed adding, "The showroom from where we bought the car, arranged the registration."

Meanwhile, the luxury Infiniti SUV of Harris Chowdhury, which had been seized by the authorities on Wednesday, was handed over to Dhanmondi police on Thursday. Harris' name is on the list of 50 corruption suspects published by the Anti-corruption Commission.

Police are interrogating a brother-in-law and the chauffeur of Harris, who were also arrested during the confiscation. A Dhaka court sent them to a three-day remand on Thursday.

The luxury Range Rover, imported by former state minister for communications Salahuddin Ahmed and confiscated from Mohakhali on Sunday by the authorities, is being kept at Shilpanchal PS in Tejgaon in the capital.
