After 20 cars were left damaged on Saturday, two 18-year-old men have been arrested and bailed on suspicion of criminal damage.
Police were called around 4.40am on Saturday, May 14, to reports of two people knocking wing mirrors off cars in the Ballingdon Street area. Officers attended and found a number of vehicles with damage.
One of the 18-year-olds, from Sudbury, was arrested in the area before 5am, the other, from the Halstead area of Essex, handed himself in a short time later.
Both were taken into custody where they were interviewed in connection with the incidents.
Both have now been bailed to return to Bury St Edmunds Police Investigation Centre at the end of June to allow further enquiries to be carried out.
