An Oskaloosa man and three juveniles have been arrested in connection with a series of thefts from vehicles in Pella.  On October 24, Pella Police responded to a call of a vehicle being burglarized.  After a search of the area, 19-year-old Alexander Baker of Oskaloosa was arrested and charged.  A week later, investigators determined that Baker and three juveniles had worked together to commit four burglaries and thefts from vehicles. Pella Police say all the vehicles were unlocked and had valuables inside.  Baker is charged with four counts of third degree burglary from a motor vehicle and four counts of fifth degree theft.  The juveniles, who are from Searsboro, University Park and Barnes City, are facing the same charges.
