Michigan law enforcement officials are trying to determine how an election campaign advertising sign became booby-trapped.

Oakland County Sheriff’s Office is investigating a complaint about a Trump 2020 campaign sign that allegedly had razor blades added.

An election worker claimed his hands became seriously injured while relocating political signage in Commerce Charter Township, 33 miles northwest of downtown Detroit.

The man alleged the sign had to be repositioned because it was improperly placed near Sleeth Road and Wixom Road, obstructing the view of those who needed to yield the right-of-way.

According to the Daily News, local ordinances require all political signage to be at least 33 feet from the center of the road, and the corrugated sign was claimed to be 9 feet too close.

On closer inspection, he found several razor blades sticky taped along the bottom edge of the board. He eventually drove himself to the hospital, where he allegedly received 13 stitches to his fingertips.

“Anyone passing by could have grabbed hold of the sign and been injured, a kid, a dog walking, whatever the case may be,” Commerce Township Supervisor David Scott told Fox 2 Detroit.

In the past, Scott saw similar measures introduced to deter anyone passing by from interfering with the position of signs.

“You cannot booby trap signs with the intent to hurt someone,” he said. “I have seen signs that have been tied to a tree, chained to a fence post or a mailbox, preventing them from being removed. This was simply laid out to hurt someone—and it did.”

However, the homeowner does not know who attached the razor blades and only remembers all of the signs disappearing before leaving for a trip. They were returned once she returned home from traveling, according to the Daily News.

Officials confirmed with the paper “several” signs with razor blades attached were found and removed from the property.

Anyone with information about the incident is asked to contact the Oakland County Sheriff’s Office by phoning 888-350-0900 or visiting www.oakgov.com/sheriff.

Michigan Gov. Gretchen Whitmer was recently criticized for ordering “perimeter security and other safety upgrades” to be fast-tracked for her state-owned mansion in Lansing, 96 miles northwest of Detroit.

The governor’s office would not reveal precisely how much the fence would cost and instead confirmed the executive office budget had allocated $1.1 million to maintain the Michigan Governor’s Mansion.

“Routine maintenance and upgrades are performed as needed to ensure the safety, security, and protection of any sitting governor and the first family,” the governor’s spokeswoman Tiffany Brown said, according to the Detroit News.

The announcement was unusual since Whitmer had been a vocal opponent of the Trump administration’s U.S.–Mexico border wall project back in 2017. The governor’s decision to build herself a perimeter appears to be at odds with her earlier position.

“$40 billion for the [border] wall,” she said at the time on Twitter. “Think how many kids that would educate, how many roads, bridges, and pipes it would fix.”

Whitmer also campaigned against President Donald Trump’s wall in 2018, saying, “It is time we get back to building bridges, not walls,” according to the Daily Wire.
