SANTA CLARA -- A site superintendent at the new 49ers stadium is facing charges of stealing copper wire valued at more than $500,000 from his employer.

Vincent John Latona, 37, an employee of Cupertino Electric, was formally arraigned Thursday with seven felonies, including five counts of grand theft by an employee and two counts of commercial burglary, said prosecutor Victor Chen of the Santa Clara County District Attorney's Office.

Latona is scheduled to appear in court Monday for a plea hearing.

Chen said the audit into how much material was stolen is ongoing. Prosecutors believe the thefts goes back to 2009.

Latona was arrested Monday at 11 a.m. at the stadium construction site, according to a Santa Clara police arrest log.

Prosecutors believe Latona stole copper wire from Cupertino Electric. The wire was not taken from the stadium project site itself, Santa Clara police Lt. Kurt Clarke said.

"We are aware that an employee of Cupertino Electric, a subcontractor on the stadium project, has been arrested for theft from his employer," wrote Turner/Devcon, the project's general contractor, in a statement. "This employee has performed work on Levi's Stadium and, while it does not appear there have been any fraudulent charges to the stadium project, we will await the results of the investigation before commenting further."

Devcon/Turner said the contractor's invoices will be reviewed by auditors to see if there were any inappropriate charges. If so, they will be recovered from the contractor.

"Neither the Stadium Authority nor the 49ers will incur any cost in this regard," Devcon/Turner stated.
