Police are still searching for a teenaged girl they say hit an Asian woman in the head with an umbrella on an MTA bus in The Bronx — while yelling that the woman had “caused the coronavirus.”

The hate crime attack took place on a Bx13 bus on March 28, a Saturday, at around 3 p.m.

The suspect and three 15-year-old girls allegedly approached a 51-year-old Asian woman as they rode together through the Highbridge neighborhood.

All four attacked the victim, calling her “bitch” and asking why she wasn’t wearing a mask — and blaming her for the global COVID-19 outbreak, police said.

They fled the bus after the attack, police said.

The victim was taken to a local hospital and received stitches for a cut to her head, police said.

The three 15-year-olds were apprehended near the scene shortly after the incident.

They face charges for hate crime assaults, menacing and harassment.
