A piece of advice for would-be purse snatchers: Don’t mess with the lady who organizes the meet-and-greets with the police.

Plain-clothes officers nabbed two teenage purse snatchers on bikes after they grabbed a shoulder bag from longtime resident Fran Byers near 48th and Baltimore at about 2 p.m. on Monday. That’s the same Fran Byers who organizes the monthly community meeting with officers from the University City Division of the 18th Police District. In fact, she was passing out flyers for the meeting when it happened. The teenagers rammed Fran from behind then grabbed her bag, pulling it so violently that her shoulder was dislocated, according to friends.

Fran won’t be at tonight’s meeting, which begins at 6 p.m. at the usual spot in the basement of the Calvary Center for Culture and Community (801 S. 48th St.) The meetings provide an opportunity for residents to share information and concerns with police about crime and neighborhood issues.
