"We got a hit. Four people have been arrested, and quite a lot of stolen goods have been found," said Johan Johansson, officer on duty at the Halland police force, to news agency TT.
The arrest was followed by a thorough search of a car and a house. The police also suspect narcotics offenses.
The Halland police focused the night's stake-out on Melbystrand and Knäred, the neighbourhoods that have been hardest hit by the recent crime wave. Suspicion arose when they saw a group of people outside a car, and this led to the arrest and the search.
All four arrested were already known by the police.
Halland is one of the regions in Sweden which has been suffering most from the recent wave of break-ins.
"We've had twelve burglaries just since Saturday noon," said Johan Johansson on the night between Saturday and Sunday.
He hopes that this arrest will lead to some of these being solved.
