Police say the suspect grabbed the woman's pocketbook and hit her in the face before running off.

Last night, investigators say another woman had her pocketbook stolen on Atherton Avenue in Elmont. Police say the thief hit the victim in the head, grabbed her pocketbook and threw her to the ground before taking off.
