Six people were arrested and booked into the Salt Lake County Jail Thursday after police say they were operating a car body shop without a license.

The leader of the group was actually arrested for the same crime in September, but later failed to show up for court and had a $5,000 warrant issued for his arrest. In the meantime, the man apparently went right back to running his illegal business, said Utah Motor Vehicle Enforcement Division spokesman Charlie Roberts.

The group was renting warehouse space on Redwood Road but was not even operating under an official name. They simply posted a sign out front saying, "Body shop and fine detailing."

Operating a body shop without a license is a misdemeanor. But Roberts said additional charges — some that could rise to the level of a felony — are pending, as well as additional arrests. He did not disclose any more details. Roberts said the group was not operating a full-scale chop shop, but there was some car dismantling happening.

Other agencies are part of the on-going criminal investigation, he said.
