Police are appealing for information after three business premises in Rougham were targeted by burglars.
They took place at the Industrial Estate overnight between Tuesday and yesterday.
The first involved a back door being smashed and items, including a CCTV hard drive, were stolen, along with a yellow and red Vauxhall Movano van - registration number AY02 KLM - which was driven out through a roller shutter door, opened from the inside.
The stolen van was then used to carry out the second break-in.
It was driven into a secure yard after the padlock was cut off a set of gates.
A door into the building was then forced and numerous tools and electrical equipment were stolen, along with a black Porsche Carrera - registration number 864 DOF.
The third burglary saw the offenders cut a fence to enter another yard and try to force their way in through a window.
But they were prevented from gaining access due to metal bars being in place on the inside.
Anyone who witnessed suspicious activity in the area, or who believes they may have seen the stolen vehicles should call Bury St Edmunds CID on 101 quoting reference BR/14/477, or Crimestoppers, anonymously, on 0800 555 111.
Business owners are advised to regularly review the security of their premises, ensuring that perimeter and building security is robust and of a good standard. This includes fences, gates, doors, windows and locks.
They are also advised to check intruder alarms and CCTV systems are in good working order. CCTV hard drives should be concealed and kept within a secure unit inside the building.
