A Trinity International University student has been arrested and charged with sending racially inflammatory hate mail to classmates, prompting last week’s evacuation of minority students from the north suburban school, police said today.

The unidentified student is an African-American woman who was unhappy attending the Bannockburn college and wanted to convince her parents it was too dangerous for her to stay. … She allegedly admitted writing the three letters that caused the uproar and was arrested.

The Lake County state’s attorney’s office approved charges against the woman of disorderly conduct and committing a hate crime. She was in custody and was scheduled to appear for a bond hearing today at the Waukegan courthouse. …

After a third letter was received Thursday, university officials and police took the precautionary step of moving 43 students of color to an unidentified hotel.
