A Harvard University employee was arrested on a charge of theft after allegedly using a school issued credit card to purchase thousands of dollars worth of Lego, police in Massachusetts said.

Waltham police said that they have arrested 44-year-old Shawn Bunn, after being accused of spending $80,000 on Lego and other items.

Over a period of four years, Bunn used the university issued credit card for personal purchases, and then covered his tracks by filing fake receipts with the school, police said.

In addition to Lego, Bunn bought TVs, iPads, a table saw and a garbage disposal system. Bunn worked as a computer lab manager at Harvard for 17 years.
