An eighth-grader at a Centennial middle school says he's been bullied and attacked because of his German ancestry.

Fourteen-year-old Adrian Ulm grew up in Germany, but now attends West Middle School in Centennial.

He says bullies questioned whether his grandfather was Hitler, and called Adrian a Nazi. The teen says he was also a victim of theft, after other students stole a $100 calculator, markers and pencils.

Adrian was beaten last November. He said he agreed to the fight at a bus stop in an effort to end the bullying, but the harassment continued.

The boy who beat Adrian was later expelled.

A school spokesperson says officials are working with Adrian and his family to make sure he's safe.
