"It has come to our knowledge that a woman has registered an FIR against AAP MLA Jarwal. It is now established that in (Arvind) Kejriwal's party there is no space or respect for women," Bharatiya Janata Party Delhi unit chief Satish Upadhyay said.
"About a month ago a similar incident was reported from Narela where an Aam Aadmi Party office-bearer stands accused," Upadhyay said.
A case of molestation, eve-teasing and intimidation was registered on Friday against Jarwal, Additional Deputy Commissioner of Police Rajeev Ranjan told IANS.
Jarwal, who represents Deoli constituency in the Delhi assembly, has denied the charge.
The alleged incident took place on July 2, when the woman, a resident of Sangam Vihar, had gone to the Delhi Jal Board office in Greater Kailash area to make a complaint, Ranjan said.
Jarwal and his supporters allegedly molested the woman there. Ranjan said the police is currently investigating the matter.
Denying the charge, Jarwal posted on Twitter: "Molestation of women against me is baseless. It's all about dirty political game."
Jarwal was also arrested in May 2014 for assaulting a junior engineer of the Delhi Jal Board at Sangam Vihar.
It's the second such case against an AAP legislator in a fortnight. Earlier, a sexual harassment case was registered against Dinesh Mohaniya who represents Sangam Vihar in the Delhi assembly.
