Construction company Gilbane | Turner says the work of local law enforcement and calls to a tip line led them to two suspects after graffiti was found at the job site of the new Highmark Stadium.

Last week, the joint construction management team of Gilbane | Turner stated that the graffiti was discovered in several locations, both in finished and unfinished areas of the project site. The group said work was suspended and a full investigation was launched in partnership with contractors and unions. Work resumed on Friday.

Authorities are still actively investigating the case.

“The Gilbane | Turner team has worked diligently to create a respectful and supportive environment on this project. We have made significant investments in jobsite amenities to support the trade workers performing demanding work, often in challenging weather conditions. They deserve a professional and respectful workplace,” Gilbane | Turner said in a statement. “The actions of a very small number of individuals do not reflect the values or conduct of the approximately 8,000 people who have worked on this project to date. They demonstrate professionalism, pride, and respect each and every day.”

The Buffalo Bills are scheduled to begin next football season at the new stadium.
