CCTV pictures have been released following the large fire at a disused building on a Malvern industrial estate.
It broke out before 5pm on Tuesday at the property in St Andrews Road and the police have confirmed the incident was suspicious and is being investigated as ‘arson not endangering life’.
Police officers say they are keeping an open mind as to how the fire may have started and are keen to trace a group of five people shown in CCTV who were in the area at around the time the fire occurred.
The police believe they may be potential witnesses and are keen to speak to them to help progress their enquiries.
Anyone who recognises the individuals in the picture should call PC 20387 Henry Randall-Cook at West Mercia Police on 101.
