DENHAM SPRINGS — Federal agents have temporarily closed Calmes Motorsport, which is under investigation by the Internal Revenue Service Criminal Investigations Division, an agency spokeswoman said Wednesday.

Janet Magee, an IRS CID spokeswoman, would not confirm any details about the investigation of the Florida Boulevard business, except to say agents were there “on official business.”

Armed agents in bulletproof vests could be seen walking around the store Wednesday morning.

Magee could not say when the store would reopen.
