Burglars have stolen £300,000 of computer equipment from a company's Crawley offices.
The thieves broke into a building owned by BOC Edwards at the Manor Royal Industrial Estate between 8pm on Sunday and 3.30am on Monday.
The haul included 45 desktop computers, 39 laptops, nine PC servers and a palmtop computer, worth a total of about £300,000. The thieves also damaged doors.
BOC Edwards, which also has plants at Burgess Hill, Eastbourne and Shoreham, makes vacuum systems and pumps.
A police spokeswoman said: "Given the amount of equipment taken, at least one vehicle must have been used."
In May last year, the firm's Eastbourne factory was gutted in one of the largest fires seen in the town.
Witnesses should call Sussex Police on 0845 6070999.
