Agents from the U.S. Postal Inspection Service arrested a man in Worthington earlier this month as part of a federal investigation involving a long string of mail thefts in central Ohio.

Worthington Division of Police officers were called to the corner of High and Short streets at 1 a.m. July 9, according to reports. The daily report summary said Worthington officers "assisted the postal service in arresting multiple subjects for mail theft."

Sgt. Jim Moran said the case was being handled by postal inspectors and he could not reveal any information on the person or persons arrested.

However, he did say Worthington police officers took a 15-year-old boy and 17-year-old girl from Dayton into custody during the arrests.

In an email, U.S. Postal Inspection Service spokeswoman Kathryn Woliung said her department was "unable to provide any specific information" about the case or any arrests because of "an ongoing federal investigation."

She said revealing any information "could jeopardize the investigation."

Tim McCall, a postal inspector, said the case was being prosecuted federally and the arrest or arrests were made under a federal warrant.

Since early 2017, many residents of Worthington and surrounding communities have reported payroll checks being stolen and forged.

From July 1 to 19 alone, police have received 10 reports of stolen, altered or forged checks that they discovered were intercepted or stolen from mailboxes. The thefts have been under investigation by the local office of the U.S. Postal Inspection Service for at least a year.

Despite 13 people being indicted on mail-theft and bank-fraud charges in October 2017, Moran said, the case still remains open and is being investigated.

He said he hopes residents would begin avoiding unsecured outdoor mail drops.

"People need to be aware that there's a situation that's being investigated," he said. "Mail your mail inside the post office."
