Tiwari and his supporters allegedly got into a scuffle with AAP members and police at the inaugural event of the newly-built Signature Bridge here on Sunday.
AAP's East Delhi Lok Sabha seat in-charge Atishi Marlena alleged Tiwari had gone to the venue for "rioting".
"Police was directly or indirectly involved in it and allowed Tiwari and his supporters to reach the stage where the chief minister and other ministers were present, thus posing a threat to their security," she said.
The Delhi government is also exploring legal options in view of the Delhi police's "failure" to keep "BJP's hooligans" away from the venue, he added.
The BJP had on Sunday said that AAP MLA Amantullah Khan used abusive language and pushed Tiwari.
Panday said Khan did it to prevent Tiwari from getting onto the stage.
"Khan should not have pushed him. He was only trying to stop him from coming onto the stage, where Kejriwal and other leaders were present," he said.
