Police are appealing for the owner of property handed to them to contact them.
Three bags of recording equipment and about a dozen tapes were left in Alderford Street, in Sible Hedingham, last Tuesday and were handed in to Halstead police station at about 8pm.
It did not look as though they had been left on the road for a long time.
The owner is encouraged to contact police on 101, quoting reference number 1014200115.
