Potwin ? Burglars have struck a post office in a south-central Kansas for the second time in a year.

The latest break-in at the Potwin Post Office happened sometime between 5 p.m. Wednesday and 7:30 a.m. Thursday.

Butler County Sheriff Craig Murphy said Friday that a desktop computer and the keys to a number of post office boxes are missing.

The Augusta Daily Gazette reported that deputies found the front door had been forced open. Both the latest burglary and the earlier break-in remain under investigation
