Congress leaders accompanying her got into a fight with security personnel.
"She did not have any entry pass. We stopped her for security reasons," a security official told news agency IANS.
The woman, accompanied by her father and senior Congress leader Sunil Jakhar, said she had come to the assembly to demand justice.
A few days ago, the woman was filmed on a cell phone by a passer-by as two policemen hit her repeatedly near Amritsar. "Was she a terrorist?" the Supreme Court asked earlier this week as it demanded information on how the cops involved had been penalized. A few hours later, the two policemen who were seen on camera hitting her were arrested.
The woman's family claims she was attacked when it tried to complain to the police of her sexual harassment by some drivers. The police say she was trying to obstruct the arrest of her father, who was drunk and causing a public nuisance. However, they agreed that the attack on her was unjustifiable.
