The incidents, in the Glencar area of Letterkenny, took place in just a 20 minute period.
TVs, playstations, handbags, and personal items were all stolen in the raids.
The experienced criminal gang went ‘door to door’.
They then made their escape in two cars stolen in the same area. One of them was later found burnt out in Drumkeen in the early hours of Sunday morning.
Donegaldaily.com understands that Gardai already suspect a number of thieves with lengthy criminal records.
One suspect was recently released from prison, having served time for similar offences.
Most of the homes which were raided were in Gleann Rua.
“This was an orgy of mindless thuggery,” said one Garda, “it was just wanton theft and vandalism on a dreadful scale.”
Gardai in Letterkenny are seeking help in catching the criminals.
