Auckland, Feb. 9 (ANI): In an unprecedented move, New Zealand Police, investigating the killing of Indian-origin taxi driver Hiren Mohini, has put up a bill board in downtown Auckland appealing people for information on the murder.

Detective Senior Sergeant Hywel Jones said the billboard features an image of the suspected murderer and owner of a bloodied blue bag found near the scene.

“We’re trying a range of methods to appeal to the public for information. The billboard space was vacant and its location ties in nicely with the fact we’re appealing to Asian communities in the inner city to help us solve this mystery,” the New Zealand Herald quoted him, as saying.

Jones said police have also made a DVD with a police advertisement on it and will take it around supermarkets and other shops for it to be played on in-store promotion screens.

Meanwhile, the number of investigators probing the case has been boosted to 50.

Mohini, 39, was stabbed to death by a passenger in the Auckland suburb of Mt Eden on last Sunday.

Police is suspecting a man of Asian appearance to be involved in the killing.

Police also released security camera footage of an Asian-looking man captured on CCTV in the CBD before the killing.

He was carrying a bag similar to a distinctive bloodied blue bag found a short distance from where Mohini died.

Jones said the bag and a distinctive black knitted cap in it could be vital clues in finding the killer. The cap had a large white logo outlined with three circles. (ANI)
