PROVIDENCE, R.I — Brown University spokesman Mark Nickel said Tuesday he is unable to say why Emma Watson, aka Hermione Granger in the “Harry Potter” movies, had an undercover armed guard with her during graduation ceremonies on Sunday. Graduate Watson, 24, was photographed walking next to a woman wearing a cap and gown who in other photos had no cap and gown but wore a holstered weapon and a badge.

Providence Public Safety Commissioner Steven Pare said the woman is not a Providence officer.
