Police raided a 79-year-old widow's cottage - after mistaking her tomato plants for a cannabis factory.
The officers burst in to Lulu Matheson's home in the Scottish Highlands with sniffer dogs and took samples of the plants for analysis, reports the Daily Mail.
Lulu Matheson, of Shieldaig, said: "I got a terrible fright and I couldn't understand what they were doing here because I knew we had nothing more than tomatoes in the window. I don't know what the neighbours must be thinking."
Her 47-year-old son Gus, a former driver, was looking out of the window when he saw police cars stop outside.
He said: "I wondered what on earth was going on. I opened the door and they more or less barged past, saying that I was growing cannabis on the windowsills.
"I started laughing because I knew they were tomato plants but it wasn't so funny when they frisked me and then started tearing the house apart."
Mr Matheson is now making a formal complaint to Northern Constabulary.
A police spokesman said: "We can confirm that, acting on information, we attended at an address in the Shieldaig area. No drugs were found as a result of the search."
