MAINZ, Germany — A male stripper sparked panic in Frankfurt's red-light district after being spotted with what appeared to be an assault rifle and bullet-proof vest emblazoned with "FBI."

"A significant number" of police officers were deployed to the area after Saturday night's sighting, officials said.

The 30-year-old Hungarian man was later found in a table-dance bar, where he revealed the suspicious items were part of the costume for his act.

The weapon turned out to be a plastic replica “but had deceiving similarities to a G36 assault rifle,” according to a police statement.

After a delay, the stripper was permitted to perform late Saturday, “but whether his act was a success, is not known,” police added.

“Prosecutors in Frankfurt now have to evaluate whether the possession of the rifle replica violates German gun laws,” Frankfurt police spokesman André Sturmeit told NBC News.
