Nicky said she was relieved her car had been removed from East City Towing as she didn't trust it being in their care where tow-truck drivers could "drive it whenever they liked".
Mr Gutry said police spoke to the owner of East City Towing yesterday and that they "will be following up on what he's told us. I can't go into what he's said, but we are investigating to establish what happened."
Police have also spoken to Nicky and the director of GPS tracking firm Snitch, Jeremy Mclean, because the GPS report was being used in their investigation.
Mr Gutry anticipated they would complete their investigation by the end of the week. Once finished, the police would assess whether it was appropriate to continue their contract with East City Towing that allows the firm to act on their behalf.
They have worked together for 12 years and in that time Mr Gutry said Nicky's complaint was the first they had received about the towingcompany.
Nicky believed the police needed to end their contract with East City Towing.
"When the police tow or impound something, you'd expect it to be done by responsible people.
"You think your stuff's going to be safe with someone who the police have ordered to do it."
A spokeswoman for the tow firm declined to comment further last night.
