The owner of Noah's Ark, of Stroud, Gloucestershire, confronted four would-be thieves at 4am on Thursday morning (as reported in StroudLife).
Alerted by the shop's security measures, Chris Hart drove to the shop and blocked the thieves van, which was loaded with five mountain bikes. Failing to ram his truck out of the way, they approached Hart with crow bars before fleeing the scene.
On Facebook the owner understated the event: "Bit of excitement this morning!"
