The Niphad MLA gave his resignation to Thackeray at the Ojhar airport here this morning, while the latter was on his way to Shirdi to address a rally, Shiv Sena district unit chief Jayant Dinde told PTI.
"Owning the responsibility of the toll-booth incident, Kadam tendered his resignation," Dinde said.
Video footage aired by a private news channel had purportedly showed Kadam abusing the all-female staff at the booth. Police said Kadam apparently lost his cool because the staff demanded toll from him, while the MLAs are exempted from toll. He was travelling in a private car at the time.
