Agents from the FBI and Internal Revenue Service agents converged on both locations of Warren Fabricating and Machining in Trumbull County early Wednesday.

Hubbard Township Police Officers were called out to the company's facility on Chestnut Ridge Road shortly before 8 am Wednesday.

A 21 News crew also saw armed investigators at Warren Fab's Mahoning Avenue in Warren Township.

A spokesman for the Cleveland FBI office tells 21 News that their agents are only assisting the IRS, which is in charge of the investigation.

IRS spokesman Craig Casserly would only tell 21 News that information about the investigation is under court seal and could not say more about what is going on at the offices.

Casserly said the information could remain sealed for days, weeks, or even months.

War Fab attorney Ian Friedman says the company is fully cooperating.

"I'm very familiar with the situation and can state unequivocally there is really nothing to see here," said Friedman. "This company has been a family-owned company running for generations. Everyone is like family here and we expect that once this is fully investigated it will be cleared up and business back to usual tomorrow."

Workers were sent home, but Casserly said he expects that they would be able to return later Wednesday.

The company has been in the news as recently in August when former Warren Fab Chief Financial Officer Paul Theisler, Jr. was sentenced to two years in prison for stealing hundreds of thousands of dollars from the company.

Friedman says the raid on Wednesday is not related to that case.

"The investigation last year dealt with an individual who pled guilty in court to his own theft so he's in prison as far as I know so this really has nothing to do with that. Again, we're very confident that once the U.S. Attorney's office sifts through all the documents and analyzes this that there's nothing here and this was just a precautionary measure," he said. 

Friedman released a statement Wednesday evening:

Warren Fabricating has done absolutely nothing inappropriate.

We are cooperating with all investigating authorities. We don’t yet know any details of any allegations of wrongdoing, and we don’t know the source of those allegations.

Here’s what we do know: Warren Fabricating will be open for business on Thursday, the 160 employees will be back to work, and they will be doing business the right way – just as Warren Fabricating has done business for 50 years.

We look forward to this investigation bringing out the truth – because we know the truth is that Warren Fabricating has held itself to the highest business standards and ethics. That’s how this company established its excellent reputation over the last 50 years, and it’s how Warren Fabricating will continue doing business for years to come.

We would be happy to share more information as it becomes available, but given the sensitive nature of this situation, we will not be commenting beyond this statement today.
