Chatham-Kent police are warning to ask for identification if someone knocks on your door offering to do maintenance or repairs.
That after an elderly Ridgetown woman reported that two men had offered to clean her eaves troughs but then tried to convince her that she had leaks in her roof.
The woman ordered them to leave, and they did, after leaving a bill for their work and saying they'd come back for payment.
They didn't return to her home.
