I experienced something similar in ROME some years ago..Your beggar was a GYPSI and the the technique was exactly as you describe..A pregnant woman came up to me pointing to her big stomach begging for money saying to me,me Bambino ,me bambino while her accomplace came around behind me and tried to pick my pocket ..I slammed her hand down and pushed her away. I was warned to be carefull with that type of beggar .They are also known a “ROMA” in Europe..
GYPSI’s… While in Italy about to board a train to some Italians made a point to warn me to be carefull ..many gypsies pickpockets were roaming around ROME at that time. I was an obvious tourist and the Good Italians knew I would be a target so they made a point to caution me ….
