Wayne Cousens, 49, whose job was to guard diplomatic premises, kidnapped marketing director Sarah Everard on a London street as she was walking home from visiting a friend last March, using his police powers to force her into his car.
Her body was later found in a forest about 50 miles (80 km) in the southeast of England.
His actions sparked anger at the failure of the police and society at large to tackle violence against women, and he was told that he would go to jail for life with no chance of parole.
The Crown Prosecution Service said it has now authorized Cousins to be charged with four more alleged crimes of self-disclosure that took place less than a month before he attacked Everard.
“Following the handover of evidence by the Metropolitan Police, the CPS authorized four charges of indecent exposure against Wayne Couzens,” said Rosemary Ainslie, head of the CPS Special Crimes Squad. “The four alleged crimes were committed between January and February 2021.”
He is due to appear before London’s Westminster Magistrates’ Court on April 13.
In January, the government announced that there would be a public inquiry into whether Cousins could have been stopped before he killed Everard.
Her death led to public rallies and an outpouring of anger from women who spoke of their own experiences and fears of being alone at night.
The High Court in London ruled last week that the police acted unlawfully when they used Covid-19 regulations to force campaigners to cancel a picket in honor of Everard, which ended with officers using heavy-handed tactics to arrest several women and drawing widespread condemnation.
