Police have stepped up patrols in the Upper Dales after Hawes was targeted by thieves earlier this month.
Thieves stole from sheds and vehicles in the town last Monday night or early Tuesday morning.
Inspector Mark Gee, neighbourhood inspector for Richmondshire, said enquiries were still ongoing and no arrests had been made yet.

However, he said patrols of both marked and unmarked police vehicles had been increased to both deter and detect crimes being committed in the area.
Officers were also working with Rural Watch volunteers to keep an eye out potential incidents in the area.
Insp Gee said thieves could potentially use the dark nights to commit further in Richmondshire and he urged householders and businesses to ensure their homes, garages and out-buildings are locked.
He said: “As the clocks go back we would urge everyone to make sure their homes, sheds, garages etc are secure.
“It’s not just at night they need to be locked – it may be dark by the time people get home from work soon and out-buildings need to be locked up at all times.”
During last week’s road on Hawes, thieves broke into two vans, including one which was broken into previously about a fortnight earlier when around a thousand pounds worth of tools were taken.
In another incident a child’s bike and helmet, a hoover and a radio were taken from a shed.
