The CNH plant on Durand Avenue has been declared clear and employees are back at work after company officials there received word about a suspicious threat.
Patch received a call from someone close to the situation who said the bomb threat may have been found in the women's bathroom. According to the caller, the message detailed four bombs scheduled to go off at 7:30 am. Mount Pleasant Police and members of the CNH plant supervisory team conducted a sweep of the facility and didn't find anything.
Employees were reportedly allowed back to work shortly after 9 am, MPPD Captain Brian Smith confirmed. He was not able to confirm where the threat was discovered or what it said.
"I can't confirm at this time any of the details of the threat," he said. "The incident remains under investigation and we're working to identify the suspect or suspects."
Mount Pleasant Police Friday confirmed that officials at CNH received what turned out to be a bomb threat at 7 am. The building was cleared immediately and the MPPD was called in to help investigate.
The employee entrance was blocked and cars were being turned away to park elsewhere. Workers milled about in a parking lot across the street told only they should contact their supervisor.
Multiple teams of Mount Pleasant officers were sweeping the building with members of the plant supervisory team.
"It's a large building, and this is going to take some time," said Smith. "But any threat is serious and we need to determine first if its legitimate."
Melanie Bish, human resources manager at the plant, and Rick McPherson, corporate human resources, spoke to employees.
"We have evacuated the building and waiting for the sweep to conclude," McPherson told them.
Once the sweep finishes and if they're given the all-clear, employees will be back inside.
Smith said South Shore Fire Department and the Racine County Sheriff have been notified and are standing by in case they're needed.
