A Brown University spokesman says he is unable to answer questions about why Emma Watson had an undercover armed guard with her during graduation ceremonies.

The 24-year-old British actress, best known for her role as Hermoine Granger in the ":Harry Potter" movies, graduated from the Ivy League university in Providence on Sunday.

She was photographed sitting and walking next to a woman who was wearing a cap and gown. other photographs showed the same woman without a cap and gown, with a holstered weapon.

Providence Police Chief Steven pare says the woman is not a Providence officer.

When asked if she was a campus police officer and why the guard was necessary, Brown spokesman Mark Nickel said today he was unable to help.
