It's a story of modern technology and its use in catching criminals, sometimes directly in the act.

Last week, Manayunk resident Brian Taylor posted to Reddit that a thief had stolen a package from his doorstep, near Green Lane, in broad daylight. However, Taylor was able to post several clear pictures of the perpetrator- a white, balding man, probably in his early 30s, smoking a cigarette with a t-shirt draped over his shoulder- to the Reddit page. More than one comment on the thread reported similar thefts in nearby parts of the city.
