Gardaí have urged members of the public to refrain from leaving their personal belongings on display following a string of thefts over the past seven days.
The warning comes as detectives look to solve up to eight individual cases at various locations across the county.
Five of those incidents took place in Abbeyshrule in a trend investigating gardaí believe may be linked.
Most of those episodes resulted in a series of items being taken from cars overnight and during the early hours of the morning.
One of those saw several power tools stolen from a red Fiat Skudo van at the south Longford village's Corncrake Meadows estate.
They included a screw gun, an impacter, three batteries, a jigsaw and a grinder, all of which had the American manufacturer DeWalt logo attached.
At around the same time, a nearby private house was similarly targeted, culminating in the theft of a pair of children's scooters.
A short distance away, at the Barley Gardens estate, thieves snatched a Tanaker leaf blower from a white Mercedes Benz van.
Gardaí believe all three thefts occurred between the hours of 11pm last Wednesday (October 12) and 6am the following morning.
Meanwhile, Gardaí are also looking to piece together the circumstances behind thefts from two vehicles that were parked in Abbeyshrule village between the hours of midnight last Wednesday and 8:30am on Saturday (October 15).
That saw a white USB key with Viber, an Apple charger, a Garmin 255 Sat Nav, a USB adaptor and a Samsung charger all being reported missing.
A few miles up the road in Kenagh, vandals set a Hymac digger alight in a case of criminal damage that gardaí are especially anxious to unravel.
A fire extinguisher that was contained inside the black and orange digger's cab was also vandalised.
Gardaí believe this incident, which occurred on a bog at Derrahaun, Kenagh, took place between 2am and 2:50am on Sunday.
In Longford town, thieves made off with 12 alloy wheels from a business premises along the main Dublin Road last Thursday morning.
A VW Polo, Passat and Jetta all had their wheels removed between 1:30am and 2:30am, with some damage to the vehicles also being reported to gardaí.
A similar case of theft was also discovered in the town's Farneyhoogan estate on Monday.
This time however, the item of choice was an undisclosed sum of cash, taken from a car coin-holder between 2am and 6:30am.
Separately, gardaí are investigating a burglary which occurred at a business outlet along Longford's main Athlone Road on Monday.
Gardaí are satisfied that those responsible broke into the building via a rear door before fleeing with a black-coloured Acer laptop.
Anyone with information in relation to any of these incidents is asked to contact Longford Garda Station at (043) 3350570.
