A purse-snatching duo that has robbed seven women in less than a month in the South Shore is on the prowl.

Nassau County police described a definite “robbery pattern” yesterday as they released descriptions of the two suspects and urged some basic precautions for female drivers.

Between Oct. 23 and Nov. 13, the muggers struck Baldwin twice, Levittown, East Meadow, Merrick, North Merrick, and Wantagh. Detective Lt. Kevin Smith said the perpetrators followed the victims from a store or a bank and one of the suspects corners women in their driveways.

“They literally rip the purses from their arms,” said Smith. “Some have been pushed to the ground.”

While none of the injuries were serious, Smith said the women lost cash, credit cards, and cell phones.

The suspects are described as two black males in their early to mid-20s, one approximately 5-foot-4 to 5-foot-6 with a thin build, the other 6-foot to 6-foot-2 with a medium build. The men wore dark clothing and drove a dark four-door sedan.

Smith said residents should keep an eye on their rearview mirror to see if they’re being trailed. If so, they should contact police immediately before stopping or returning home.
