TULSA, Oklahoma - Police are looking for those who stole from more than a hundred post office boxes in Tulsa and Owasso.

All day Saturday people were flooding into the Owasso post office, trying to find out if they too were victims of this mail theft. Postal employees came in to find several boxes open and empty early Saturday morning.

Victims left with no mail, and a lot of worries. 

Charles Jennings was one of the victims whose box was open and empty. 

"They knew what they were doing; a thief is low down plague on our society," Jennings told News On 6. 

He says the box belonged to his Christian ministry, and there were possibly donations inside.

"Therefore we receive donations, mainly checks, and I checked the box Thursday so hopefully there were no checks in there, but who knows."

All the victims, including Bill Kelley's box, had appeared to have been pried open.

"They busted up the lock and everything on ours," Kelley observed. "We don't have any mail and it looks like the screws are out of it and everything."

Lieutenant Nick Boatman with Owasso Police said it took only minutes for the crooks to break into more than 60 boxes.

"The lobby of the post office all hours of the day," said Boatman. "Unfortunately that allowed the person to do this to get in unrestricted and pry open boxes." 

Thieves also broke into the Utica Square Post Office in Tulsa overnight. Boatman says he can't confirm if the two are related and is working with Tulsa Police and the postal inspector for what could be an ongoing issue in the area.

If something is missing from your post office box, contact the post office inspector.
