RICHMOND, VA (WWBT) - It all started near First and Marshall Streets on a bus that serves Downtown and Northside.
Right now, both the police and GRTC are investigating, and so far authorities say they don't think this was a criminal act.
The state lab determined Tuesday the liquid is a strong base on the pH scale. Authorities said they will never know for certain unless the person responsible for it comes forward telling them what it was. Police said they still believe it does not involve any criminal conduct.
According the Richmond Times Dispatch, police, firefighters and a hazmat crew responded to this incident.
The girl, who says she didn't notice anything unusual until she sat down, was taken to VCU medical center for second degree burns on her knees.
Three seats were taken off the bus, and samples of the liquid on them are now at the state lab. Initial testing showed the liquid was some type of acid.
What kind of acid it was, and where it came from is still being investigated.
The bus involved in the scare was taken out of service yesterday, and routes will be normal today.
