A donation from a local business, and a city resident's volunteer contributions, are helping the department spread its message to three busy locations in the city.
Lamar Advertising provided Sandusky police $6,000 for billboard space to launch a campaign focused on curbing crime.
Dubbed "Stop the Violence," the campaign aims to remind commuters about reporting crimes, and it provides them with contact information for local law enforcement or social service agencies.
The messaging comes as a result of recent violent crimes in Sandusky, including six murders since June.
"We formulated a message that we felt would promote involvement in the community in assisting the police department with some of the violence that has taken place over the past year," Sandusky assistant police Chief John Orzech said.
Orzech is asking community members to report all crimes, but particularly those involving domestic violence; child abuse; weapons; and burglaries and robberies.
"We want to make Sandusky a safer place for everyone, and focus on those who become victims to these incidents," he said. "Community involvement by the citizenry is essential to 'Stop the Violence.'"
