PORTLAND (AP) — Police are looking for a robot that was stolen from a Portland State University professor.

The Washington County Sheriff’s Office says physics professor Erik Sanchez reported the theft Monday. The 90-pound robot had been in a car parked overnight in Aloha.

The robot is 29 inches long, 19 inches high and about 23 inches wide. It is valued at $5,000 and was donated to Sanchez by the manufacturer for use as a teaching tool in one of his classes.

The sheriff’s office says it is following leads, but asks anyone with information to call detectives at 503-846-2500.
