An FBI-themed stripper party shut down a red light district in Germany this weekend after cops thought one of the dancer’s was packing real heat.

Police spotted the 30-year-old male exotic dancer Saturday night when on his way to shake his booty at a Frankfurt club clad in a bulletproof vest that had “FBI” on it, and holding fake assault rifle.

The get-up caused a “significant number” of cops to swarm the area, according to NBC News.

They were initially concerned about his gun, which police said “had deceiving similarities to a G36 assault rifle”, but turned out to only be a plastic prop.

The bawdy show did go on, as cops allowed the stripper to perform later on that night.

But authorities are now looking into whether toting a fake weapon violates any of Germany’s tough gun laws, cops told the network.
