The Delhi police on Monday registered a first information report against those who fudged evidence in the Jessica Lal murder case.
A special team has been set up to investigate the case.
A Delhi court had recently acquitted all those charged with the murder, including prime accused Manu Sharma, son of a Haryana minister.
"We have registered a case under Section 120 of the Indian Penal Code for criminal conspiracy, for destruction of evidence and tempering with the evidence," Paul said.
He also made it clear that the police will also approach the Delhi high court against the acquittal of the nine accused, including prime suspect Manu Sharma by the trail court.
Jessica Lal was murdered on the night of April 29-30, 1999, allegedly by Manu Sharma, when she refused to give him a drink.
According to a senior police official, the fresh probe will not spare anyone and even senior police officers who had investigated the matter earlier could be brought to book.
Jessica's sister Sabrina Lal said she was satisfied with the bold stand taken by the Delhi police chief.
"I hope things move in the right direction and the culprits are made to pay for their crime," Sabrina told rediff.com.
