(CBS) — A South Side towing company under investigation by police following reports by CBS 2 is fighting back.

CBS 2’s Roseanne Tellez reports tow trucks were hauling cars once again at Rendered Towing in Bridgeport on Monday.

Officers seized 11 tow trucks Friday, complete with cameras and GPS, as part of an ongoing investigation into complaints of illegal towing practices.

“Nowhere does it say we need to have trucks with GPS, with cameras, we put that on ourselves so if a complaint would come in, we can handle it,” said Rendered Towing Manager Maria Fedele.

Just last Thursday, Deidra Simpson-Torres complained to CBS-2 that Rendered towed her car from a legal spot and had surveillance video of her own to prove it.

“Nothing by the city of Chicago thatsays you cannot park here,” Simpson-Torres said.

“If we get called to come and he says it’s my property and they know not to park there, we tow the car I don’t think he did anything illegal,” said Fedele.

Police sources told CBS-2 police also recovered eight cars from Rendered on Friday that are reported as stolen. The manager says she feels bad for company employees off the job as the investigation continues.

“These people need to work as well. Everybody has got families. If there’s a rotten apple, find the rotten apple. Don’t assume everybody is guilty,” she said.

Today the company is operating only two of its’ own trucks and the rest are still in the hands of police.

The Illinois Commerce Commission says out of 52,000 tows in the last two years, Rendered has received about 800 complaints.
