A towing firm that ruined Texas-OU weekend for dozens of drivers had its license revoked by Dallas City Hall on Tuesday, less than a month after the firm pulled away cars parked near Fair Park.

In a letter sent to Lone Star Auto Services on Tuesday morning, city officials concluded that the company engaged in a pattern of disregard for city ordinances, not only during the Oct. 11 football game but for years.

"This is a company that is just not interested in following the rules," said John Brunk, assistant director of Dallas' Public Works and Transportation Department.

The city's action may not be the last trouble in which Lone Star finds itself after the debacle at Fair Park.

City officials confirmed that the Texas attorney general's office may be ready to take similar action against Lone Star. If the company loses its state license, it will be out of the towing business everywhere in Texas.

Calls to Lone Star's office in Dallas were not returned Tuesday.

In prior statements, Lone Star officials have defended the company's actions during the Texas-OU game.

But the company also agreed to refund $200 to 26 drivers after enormous public outcry and pressure from Mayor Tom Leppert.

Mr. Brunk said that after the city reviewed Lone Star's history, it was clear the company's problems ran much deeper than one bad weekend.

Overcharging, faulty signage on property, towing from lots where it didn't have permission and failing to report tows to the Dallas Police Department were just part of a pattern of contempt for the city's towing rules, he said.

The city of Dallas limits towing fees to $95. With additional state fees and other taxes, the bill can run up to $148.

Yet Lone Star frequently charged drivers more than that, according to city records and complaints from drivers.

There were also accusations from drivers that they were scammed during Texas-OU weekend. Many reported being waved into parking lots outside of Fair Park by men in orange vests, only to return later to find their cars towed.

The city received 40 complaints related to towing around Fair Park that weekend. One driver said he saw a line 75 people long waiting to reclaim their cars from Lone Star's office after the game.

Even though the city has revoked Lone Star's license, it's possible that the company will be allowed to continue towing if it appeals the revocation.

First Assistant City Attorney Chris Bowers said he fully expects an appeal, though the city had not received notice of one late Tuesday.

Lone Star has 10 days from Tuesday to file its appeal. After an appeal is filed, the company can operate during the appeals process, which must be complete within 60 days under city ordinance.

Meanwhile, it is also possible that Lone Star may be out of business, but its owners won't be.

In Dallas, a business can have its license revoked, but the owners can reincorporate under a different name and seek a new license.

"We do recognize that our ordinance is not as strong as it could be on that sort of issue," Mr. Bowers said.

He anticipates that his office will soon bring a recommendation to the City Council to tighten those rules.

State rules related to reincorporating are stricter, officials said.

As for other towing companies around town, Mr. Brunk said the city isn't targeting anyone else at this point.

But he added that what happened to Lone Star should be taken as a message.
