If you need help busting a thief, there's definitely an app for that.
Police say Brian Chattoo, 23, was arrested Friday after allegedly stealing an iPhone from a woman.
Investigators say he bumped into the woman on a Queens street Monday night and stole her phone.
However, the phone was equipped with an app called "iGotYa," which automatically took this photo of Chattoo when he tried to unlock it.
The photo was then e-mailed to the woman who gave it to police.
Chattoo is charged with grand larceny and criminal possession of stolen property.
