As part of an effort to cut crime at the Alewife MBTA subway and bus station in Cambridge, transit police placed a cardboard cutout of a police officer in the bicycle cage. Hundreds of people use the racks daily.
Deputy Chief Robert Lenehan says the fake cop, along with video cameras and a new lock, has cut bike thefts by 67 percent.
It's also a money saver. Lenehan estimates it would cost $200,000 a year to have an officer watch over the cage full-time.
The cutout is actually a picture of real MBTA Officer David Silen.
Silen says the split second thieves take to glance at the cutout is enough to discourage them.
