Hannah Harris, 68, has been charged with two counts of grand larceny and one count of criminal possession of stolen property.
Police said that Harris targeted Mullanes Bar & Grill in Fort Greene on Sunday, when she allegedly stole a purse from a 45-year-old woman.
Surveillance video footage shows a woman walking casually past a set of tables and taking a purse of the back of someone's chair.
Authorities believe that she's also behind the June 1 theft of a purse from the Tea Lounge in Park Slope.
"Everyone was like, 'why would an old lady steal a purse,'" a Tea Lounge employee told the New York Post.
"It's just weird. You expect a teenager or a homeless person on the street to do that. Not a 68-year-old lady."
