Police are renewing their appeal for information 10 weeks after a break-in at Langley Green Youth Centre, in Crawley.
Items including a ceiling projector, an Xbox games console and several Xbox games were taken during the burglary on February 9.
Police said a man was seen running out of the centre, in Stagelands, at about 6.15pm.
The break-in happened the day after some one ripped the alarm system from the wall.
PC Maria Warren said: “Although this happened a couple of months ago now, I am still keen to speak to anyone who might have information about what happened.
“The items may have offered for sale or someone may have boasted of having taken them from the centre. If you know anything at all about what happened or who was involved please contact me.”
Anyone with information should call 101 quoting serial 683 of 8/2, email firstname.lastname@example.org or call the independent charity Crimestoppers anonymously on 0800 555111.
