About 300 of the cards have been given to suspected criminals
Christmas cards have been sent to suspected thieves by police in Northamptonshire.
The card tells the recipient police are thinking about him or her and then warns, "Don't get St Nicked this Christmas".
The cards are part of Operation Guardian, a crackdown on what police call "serious acquisitive crime".
About 300 of the cards were handed out by officers within Northampton, Kettering and Wellingborough.
'Trading on misery'
Supt Pete Windridge, who is co-ordinating Operation Guardian, said: "It's really to let them know that we are thinking about them.
"It's a message not just for Christmas, it's also a New Year's resolution.
"Operation Guardian is about safeguarding individuals, their homes and their vehicles and we are determined to bring to justice those who trade on other people's misery."
