On Wednesday evening, a woman was walking behind the Packard's Corner Star Market when, she says, she was "blitzed" from behind and knocked to the ground. The guy then ran away without attempting to take anything, leaving her shocked, with some scrapes and bruises.
Boston Police are citing her case as one of several robberies and attacks in Allston since Monday.
The attack comes several months after a still unsolved series of attacks in which a man pushed women to the ground, lifted their skirts and took pictures in the Ashford Street area behind the Shaw's.
Stories are now spreading the guy is posting photos online.
