Car keys stolen - help

[jp kelly]

ok so i drive a class 2 hgv with a crane on the back. went to a drop and went to the crane to unload the goods. in the 1 minute i was on the crane, abt 30 seconds looking away from the front, some cheeky f*** stole my work phone and my bag out of the cab and ran away without me knowing about it.
my bag had my house and car keys inside also with a letter i just got off work with my address on it, ive rang the police but they said nowt they can do so im screwed.
