Two people who Troy police were watching because they are reportedly “known” to be shoplifters were arrested recently at a Home Depot store for allegedly stealing a lawnmower — and one of them is also facing a drug charge, officials said.

According to the Troy Police Department, the two arrestees, Contel Hayden of Detroit and Nicole Cox of Lathrup Village, were under surveillance by plain clothes officers on May 14 when they arrived at the Home Depot on Coolidge Road. The store’s loss prevention workers monitored the security cameras and relayed information on the two to the plain clothes officers, reporting that Hayden had let the store with a DeWalt lawnmower without paying for it. Police said they saw Cox help Hayden load the stolen lawnmower into their vehicle, so officers approached and took them both into custody.

Crack cocaine was allegedly found in Cox’s purse.

Hayden, 63, is charged with first-degree retail fraud. Cox, 49, is also charged with first-degree retail fraud as well as possession of a controlled substance less than 25 grams. Police said the drug was found in her purse. The charges are felonies.

Both are held in the Oakland County Jail with bonds set at $1,000. They are due back in court on May 29.
