"Goonda Act will be invoked on Mustafa for raping the girl in Vibgyor High School because he has been involved in such cases in previous schools where he was employed," Siddaramaiah said in the state Assembly.
31-year old Mustafa, hailing from Bihar, was arrested yesterday after eight persons, detained for questioning in connection with the incident, were interrogated.
He said government has decided to amend the Goonda Act to include persons committing rape for the first time.
"We have sent the proposal to the Law Department and would introduce in the House as soon as possible," he added.
The government also plans to increase the number of fast-track courts to expedite cases and give speedy justice to the victim and their relatives, Siddaramaiah said.
On the demand made by YSV Datta (JDS), Home Minister K J George said the government has instructed the police to examine some steamy scenes in Bollywood film "Hate Story 2".
Raising the issue, Datta said films such as "Hate Story 2" emboldens criminals to indulge in sexual assaults.
"I request the Home Minister and the Chief Minister to examine some steamy scenes in the film, which emboldens criminals to commit sexual crimes."
Shivalinge Gowda (JDS) too asked the government to find ways to stop obscene TV serials from being aired. "These serials are not fit to be watched in the house along with the family members. The government should stop such serials."
George said government has decided to set up 10 more fast track courts in addition to the existing as many courts and Law Minister T B Jayachandra is already in talks with the Chief Justice of Karnataka High Court D H Waghela.
"This will help in speedy disposal of rape cases," he added.
He said government had also decided to set up 10 more women police stations in the state by next year in addition to as many existing ones.
"We also intend to set up women's police stations in all districts," he said.
Raising the issue during a debate on series of rape incidents in the state, Opposition BJP Leader Jagadish Shettar said the Home Minister has failed to strengthen the police force and should immediately tender his resignation.
"The police has lost its independence. There has been unnecessary interference from politicians in the working of police department," he said.
Former Home Minister and BJP member R Ashok said due to the delay in taking action against rape accused in Vibgyor and Frazer Town (where a 22-year old woman was allegedly raped) cases, government had face public wrath, which could have been avoided.
Former Education Minister and BJP member Aravind Limbavali lamented that the police has not yet booked Vibgyor school chief for delay in taking action against the accused.
"The Vibgyor chief and the management were in the know of the incident. They failed to take prompt action and tried to bury the case. The government has not taken any action against them. They should without wasting anytime punish them," he said.
