An off-road motorbike was stolen when the potential buyer drove off with it on a “test drive”.
The victim, a 19-year-old man from Worsthorne, had earlier agreed to sell the bike to a stranger, and met him in Fleetwood Road, Padiham, for the exchange.
Police said the buyer asked if he could take the yellow Suzuki on a test drive when they met at 6-30pm on Tuesday, but never returned.
The bike, which has no registration, has the number two on the front, and is valued at £2,500.
Anyone with information about the theft can call police on 101 or Crimestoppers, in confidence, on 0800 555 111.
