SAN JOSE — A Mt. Pleasant High School teacher was arrested on campus Thursday after a burglary investigation determined he stole two high-priced Coach backpacks from Westfield Valley Fair mall earlier in the year, authorities said.

Tom Tung Tran, 46, of San Jose, was booked into the Santa Clara County jail on a $10,000 arrest warrant for grand theft, San Jose police Officer Gina Tepoorten said.

Tran teaches social science and history at Mt. Pleasant, according to his teacher rating page and the school website.

He first attracted police attention following a May 28 theft of two $700 backpacks from the Coach store at Valley Fair that was captured on video surveillance, Tepoorten said. Two days later, an SJPD officer working security at the mall spotted a man resembling a surveillance image of the thief.

The officer approached and talked to the man, identified as Tran, who cooperated with an inquiry and reportedly gave his contact information to the officer and allowed his photo to be taken.

That information was submitted to SJPD burglary detectives, who built a case and submitted it to the District Attorney’s Office, which reviewed the evidence and issued an arrest warrant for Tran, Tepoorten said.

Tran was still being booked at the jail on Thursday afternoon, according to jail records.

Chris Funk, superintendent for the East Side Union High School District, refrained from making a judgment on the case, citing a need to defer to the judicial process.

“The district will take appropriate action based on findings from the police and DA,” he said.
