there isnt alot they can do to be honest , at the most we can get cid to fingerprint the car , it is most likely an addict by the sound of the break in , usually find a smash and grab robbery like this is commited by a drug addict , easy goods to sell on without trace for a fix.
Its a shame this is how it is but not alot u can do really, you prob just got hit with and incident report number and told to contact your insurance company.
70% of cars stolen in strathclyde are never found again will find they are on a "stolen to order" list , you have to realise if someone wants your car they will get it .
sorry to hear of another victim to this scum.
