ROYAL OAK, Mich. (WJBK) - Days after a frozen yogurt shop in Royal Oak receives a bomb threat, police believe they found the person responsible.
A somber face Benjamin Tesner walked out of the Royal Oak Police station after posting bond Friday.
FOX 2: "Do you have any regrets that you did something like this?"
Tesner had no answer, walking in silence with his family.
The 22-year-old was arrested after police said he made a bomb threat earlier this week to this Royal Oak business Yogurt City, where his friend works.
"Calling in and making threat of that nature has serious consequences," said Lt. Dave Clemens, Royal Oak police. "This young man is 22 years old and this is a very serious crime he will have to deal with."
Police say it's still not clear what motivated the bomb threat and no explosives were found at Yogurt City.
Investigators say Tesner still faces a number of charges which could put him behind bars for quite some time.
"It's a very serious crime making a terrorist threat - it is a 20 year felony," Clemons said. "Up to 20 years in prison."
Police are still investigating but say there is no evidence that Tesner has any ties to ISIS.
"We have not uncovered any evidence that he's associated with a terrorist group, Isis or otherwise," Clemons said. "And did not find any bomb making materials anywhere."
Tesner would not answer any questions when he left the police station Friday but his attorney had this to say
"The family is concerned that anyone felt upset, concerned or afraid," said David Nacht. "This is a good family. This is a young man who is a college graduate and normally makes good judgment calls and is nothing like a dangerous person."
Police say Tesner next court is scheduled in October.
