A couple whose B.C. Interior home turned out to be a mould-plagued former marijuana grow-op have taken their complaint to local RCMP, saying they've suffered health problems.

Theresa Denton and Kevin Dye thought everything was fine when they bought their home in Pinantan Lake, near Kamloops, but they quickly learned the house had problems commonly associated with grow-ops.

Despite one attempt at having it cleaned-up, there's still mould and Dye and his family say they were told the home was unsafe, so they vacated the property but have since returned.

Denton said there have been unexplained nosebleeds in the family.

"[Our son] had his hand on his nose and there was blood streaming down and he's the one who never has nosebleeds."

The couple has filed a civil claim in court, and has taken it to the Kamloops Rural Detachment of the RCMP with the hope there will be an investigation.

The RCMP is deciding whether fraud charges should be laid.

A grow-op's history is supposed to be marked on the realtor's property disclosure forms, but it wasn't done by the previous owner in this case.

The man that sold them the house, Robert Gillam, used to grow marijuana at the residence and was convicted for it before it went up for sale.

Gillam now lives next door to the couple, but has refused to be interviewed about the situation.

And now it appears the realty company may also have been aware of home's grow-op history.

Meg Petrie was the realtor at Royal LePage Westwin in Kamloops who first marketed the house. She told CTV News the grow-op was disclosed on the original documents.

But when she left Kamloops, her colleague Maggie Schmaltz took over the listing. The disclosure form given to the couple stated there never was a grow-op.

CTV News went to Schmaltz's home to ask for an explanation.

"She's not going to talk to you...," a man who answered the door at the home said.

So we asked the Royal LePage Westwin's office manager what happened, but Michael Mitchell said he couldn't clarify it.

"Sorry, I'd like to talk to you but like I told you over the phone, it's before the courts."

The Real Estate Council of B.C. has put its investigation on hold for the same reason.

The lawyer for Royal LePage Westwin Realty and Maggie Schmaltz says CTV News had been "duped" by Denton and Dye in that they may have added to the problem by abandoning the house after the purchase.

But the couple said they only left when they were told the mould made it unsafe to live there.

"I guess it leaves us no recourse except to take it to a judge," said Dye.

The Consumer Advocacy and Support for Homeowners Society says it's a common situation.

"The Theresa Denton case is just the latest," homeowner advocate John Grasty said. "But Hope, Surrey, Richmond, Smithers, Vancouver, Coquitlam. They're coming from all over."
