Leader of Opposition in the Delhi Assembly Vijender Gupta also demanded a through investigation into the case.
The AAP government has "gone back" on its promise to ramp up women's safety, he alleged.
"Be it molestation or rape, Delhi has seen an increase in such crimes and they have risen all the more under the Kejriwal dispensation. I want him and his ministers to focus on women's security. Where else will women feel safe if not the national capital?" Dikshit asked.
Gupta accused AAP of indulging in "big talk" while doing nothing productive on ground. He reminded Kejriwal of his poll promises including installation of CCTV cameras and deploying marshalls in buses.
"Have they implemented a single measure in reality? They are always in a confrontationist mode," Gupta said.
Dikshit said Kejriwal had repeatedly raised similar issues during her tenure to criticise her. "We are waiting for him to take some steps in this regard."
A 23-year-old Belgian woman was allegedly molested by an Ola cab driver in south east Delhi's CR Park area last night.
The accused was arrested today.
