Brighton author Peter James has given £15,000 to a Sussex Police crime prevention campaign.
The money will go towards highlighting the danger of cyber crime and how the public can stay safe online.
The bestselling crime writer said: “The modern phenomenon of cyber crime blights all our lives, from credit card fraud, cloning of identities, grooming of children to bullying on social media.
“Sussex Police provides me with some valuable insights for my Roy Grace novels and it is a pleasure to be able to give something back.”
Deputy Chief Constable Olivia Pinkney, who received his donation, said: “We’re very pleased to be working with Peter.
“We value the support he has given to Sussex Police events and campaigns over many years.”
The force said: “If you would like to make a donation to support any Sussex Police campaigns, you can find out more by e-mailing firstname.lastname@example.org.”
