BOSTON - The elderly woman who was shoved to the ground in Chinatown on Wednesday has died of a head injury.

Yuzhen Lei, 72, died at Tufts Medical Center on Thursday night, hours after her alleged attacker was arraigned and held on $75,000 bail.

The Suffolk County District Attorney's Office accuses 24-year-old Tajanetta Downing of pushing Lei after they "had some fleeting physical contact" in the area of Essex and Chauncy streets. They did not know each other.

Downing, of Jamaica Plain, was charged with aggravated assault and battery and assault and battery on a person 60 or older, and her bail on two other open assault cases was revoked. It's not clear if more charges are forthcoming. She's due back in court on Aug. 5.

Investigators spoke with witnesses after the attack and the film crew working on the new "Ghostbusters" movie directed police to Downing.

"She is distraught right now, having heard what happened," said her court-appointed lawyer, according to The Boston Herald. "This was an accident. It was not an intentional act."
