Three teenagers are charged with criminal trespassing after an investigation into yesterday's fire at the Duofold Building in Ilion, according to Ilion Police.

This is the second time since March fire crews have had to report to the former factory. On March 20th, crews fought several small fires that had been set inside the building, but didn't cause severe damage.

Yesterday's fires were small and soon contained, and caused minor damage.

The teens, two boys ages 16 and 18, and an 18 year old woman, are charged with criminal trespass.

The 16 year-old is also facing two counts each of making graffiti and criminal mischief because of an active arrest warrant. Those charges are unrelated to the investigation.

None of their names are being released because of their age.
