UPDATE:  

Two Roseville High School students have been arrested in connection with a fire that damaged the school's athletic field and destroyed the stage that would have been used for tomorrow night's graduation ceremony.

Roy Jordan Loya, 18, and a 17-year-old male have been arrested on suspicion of arson, felony vandalism and conspiracy, according to Roseville Police Spokeswoman Dee Dee Gunther.

Both of the students are seniors who would have graduated in tomorrow's ceremony. 

An overnight fire destroyed a portion of the synthetic surface on the football field and the entire graduation stage. A security guard noticed smoke coming from the field at about 1:30 a.m. and notified authorities. 

The damage to the field was significant and includes a $50,000 team logo at the 50-yard-line donated by alumnus and former NFL star Teddy Bruschi. Total damage is estimated at about $100,000. 

But school district spokesman Steve Williams is resolved that the students will get to graduate.

"Our graduation practice and our graduation ceremony will go on as planned tomorrow night," he said. 

He says the field is being repaired and a backup stage will be brought in before tomorrow's graduation activities.  

About 500 students are scheduled to participate in the graduation ceremony tomorrow night.
