People in Leicestershire who have been victims of stalking and harassment are being asked to come forward as part of a new campaign.
The police and county council are putting up posters which highlight the issue and give details of where help can be sought.
Det Sgt Pete Williams from Leicestershire Police said domestic stalkers could be very dangerous.
Stalking is harassing behaviour which is repeated and unwanted, police said.
Men and women
"It is important to recognise that domestic stalkers can be the most dangerous," said Det Sgt Williams.
"They are more likely to threaten new partners and friends of the victim and be more aggressive and intrusive in their behaviour."
Joe Orson, cabinet member for safer communities at Leicestershire County Council, said: "The effects of stalking and harassment can be devastating and men, as well as women, can be affected.
"They can take a huge emotional toll causing symptoms such as anxiety, anger, depression, paranoia and agoraphobia and can even cause victims to lose their jobs or relationships."
