The Midlothian Advice and Resource Centre on Woodburn Road was broken into and vandalised last on February 3.
Entry was gained to the property through a front window which looks out onto the busy Woodburn Road and near the two local chip shops.
The items taken were Wii and Xbox games consoles, as well as a music centre. The snooker table was also broken during the break-in.
All items belonged to the Bill Russell Youth Project which runs a Saturday night drop-in for local youngsters.
The drop-in caters for young people aged 10 to 14 years old and provides computers, games consoles, snooker, table tennis and art and crafts.
Margot Russell, secretary of the management committee of the BRWYP which is a charity set-up in her late husband’s name, said that she was deeply disappointed and angry about the break in and the theft of the games consoles. As this means that the young people who attend the BRWYP will be deprived of these activities.
Margot appealed to the local community to contact the police on 101 or Crime Stoppers anonymously on 0800 555111 if they know anything however small which may assist the police who are make enquiries and checking out CCTV cameras.
A Police Scotland spokesman said: “Police in Dalkeith are investigating following a break-in and theft from the Midlothian Advice and Resource Centre building in Woodburn Road.

“After entry was forced to the premises various pieces of electrical equipment were stolen from within.
“Inquiries are ongoing to trace those responsible and anyone with information that can assist officers with their investigation should contact police immediately.”
