This crime is by the numbers.

A binary code-obsessed thief is swiping the 0’s and 1’s from the addresses mounted on Philadelphia homes, local media reported.

Surveillance video captured one of the bizarre thefts this week, showing a woman casually walk up the front steps of an East Kensington home in the middle of the night and take the 0 from the 2202 address marker on the outside of the residence.

“We’re just very upset and frustrated and confused,” homeowner Meghan Haley told BillyPenn.com of the missing 0. “And why is it only 1’s and 0’s?”

Other neighbors have reported falling victim to the same mysterious crime pattern.

No arrests have been made.
