Allentown police tell WFMZ-TV that Scoobies Gentleman's Club has been closed voluntarily for about six weeks.
The club has been the site of several curfew violations for staying open past midnight and a fatal shooting occurred outside Jan. 26.
The fire early Monday, which caused about $30,000, is the latest incident at the club.
And now police say that was a crime, too.
Police aren't saying how the fire was set, and they've yet to name any suspects.
