(a) No person, other than a duly authorized member of the Police Department acting in the line of duty, shall alter any license plate, seal or registration card. When no serial number can be found on a bicycle or such number is illegible, the Police Department may stamp a number thereon for identification purposes. As a further aid to preventing bicycle theft or recovering stolen bicycles, the Police Department may stamp a secret number on any bicycle, at the request of the owner.
(b) No person shall own, possess, purchase, sell or in any way transfer a bicycle with a defaced or altered serial number.
