HAMILTON (WLWT and AP) —One southwest Ohio sheriff is encouraging staffers with licenses to carry to bring their weapons to work.

In a memo sent to employees last week, Butler County Sheriff Richard Jones urged civilian employees and volunteers to carry their weapons at the sheriff's office and while operating any department vehicle away from headquarters.

"Everyone should exercise some extra caution at this time concerning their own personal safety," Jones wrote.

The memo was sent after recent attacks against police officers in other parts of the county.
