This was one of the decisions taken at a special meeting of the Delhi cabinet, Kejriwal told the media.
He said the subject of increasing fast track courts would be discussed with the chief justice of the Delhi high court, and that his government would provide all help to make the courts a reality.
"The government is prepared to allocate funds to increase the number of fast track courts," he said. "We will take help from the chief justice of Delhi.
"We will need to set up many more courts. We need to speed up the legal process... We have the political will. Whatever funds and staff are needed for this, we will provide," he said.
The Aam Aadmi Party leader said one reason why attacks on women, rapes in particular, were on the rise in Delhi was because criminals had no fear of the law.
"I don't think all the bad people live only in Delhi, and that people living in places like Kolkata, New York, London or Varanasi are saints. It is just that the fear of law is not there in Delhi."
