BENSALEM, Pa (CBS) — A criminal investigation is now underway in Bensalem, Bucks County where school district officials say some employees falsified time sheets and collected money they didn’t earn.

The school district put out a news release late Wednesday evening calling it regrettable that a few employees in the facilities department have tarnished the reputation of the district. It goes on to say the district is looking at controls and protocols to prevent any further misconduct.

According to the district, the facilities department is made up of groundskeepers, maintenance workers and custodians.

Two employees have resigned and disciplinary action may be taken against others.

Bensalem Public Safety Director Fred Harran said his department is taking a close look at what happened.

“We want to do this right,” said Harran. “And make sure that justice is done and if there were any thefts that people will be held accountable.”

The school district indicated that it was an anonymous tip that led them to start looking into the possibility of wrongdoing.

“They brought this matter to our attention recently,” Haran added. “We’ve been working with them to ascertain exactly what has transpired and the scope of the incident.”

Harran said he expects it will a lengthy investigation.

“You’re dealing with a lot of individuals and you’re dealing with, you know, time sheets and time cards,” he said. “A lot of paperwork to go back and look.”

The district said it would release more information at the appropriate time, adding it doesn’t want to compromise the integrity of the investigation.
