Two teen muggers swiped the purse of a 41-year-old woman on the northwest corner of Riverside Drive and West 83rd Street. Police said that May 13 at 5:20 p.m., the woman and her children were at a nearby playground. Her husband chased the two 16-year-old boys and got the purse back. The teens also had two Razor scooters they had taken from toddlers at the playground. Police arrested the duo and charged them with grand larceny.
