Police said the incident has come to their knowledge and they are trying to contact the girl so that an investigation can take place.
"We have not received any complaint regarding this yet," a senior police official said.
In her Instagram post on February 24, the girl, who is from the northeast, said, “I went out with a friend for lunch yesterday to a café in the Amar Colony market. It was about five in the evening when we decided to head back. Not a minute of our short Metro ride had passed when there came flying my way a liquid filled balloon of sorts, hitting me square in the hip, where it burst open, its contents seeping into my kurti and leggings. It dried white on my black leggings, and the foreign smell clearly indicated that it wasn’t water.”
Reacting to the incident, The LSR Student's Union have released an official statement on their Facebook page.
