A$AP Rocky fan arrested in D.C. after threatening Swedish embassy

A$AP Rocky has fans here in the States going to bat for him -- but one chick might've taken it too far after she was arrested for storming the Swedish Embassy in D.C. ... and allegedly threatened to blow it up.

A woman named Rebecca Kanter was arrested on Tuesday after she allegedly caused a ruckus in the Swedish embassy here at home -- this a day after she allegedly threw a bunch of liquid on the front doors and said, "I'm going to blow this motherf***er up!"

The Secret Service issued a lookout warning for the lady on Monday after the alleged incident, and when she came back Tuesday ... she drew even more attention to herself by berating staff and a student group, trumpeting human rights rhetoric and seemingly arguing for Rocky's release. Authorities say she also kicked over a display and some furniture.

She was arrested on the spot and later booked for destruction of property and unlawful entry.
