Musician and producer Mark Ronson found himself offering the public a substantial "HEALTHY CA$H PRIZE" after his bag containing invaluable DJ equipment went missing from a gig. 

Tweeting anxiously, the 'Bang Bang Bang' star wrote to his 230,000 followers:

"Last nite, my DJ bag went MISSING from THE BELVEDERE in holland park. BIG reward for anyone who helps me get it back. i cant play without it"

"contact mark.gillespie@threesixzerogroup.com or on 02030517930. there will be a HEALTHY CA$H PRIZE for anyone who can get my bag back thanks"

Following a worrying lack of response, he sent out one last message that he hoped would attract a useful response that read:

"thanks for all the nice words 2day. Everything i've made since 05 is on there. about to go over the CCTV TAPES, LAST CHANCE for the reward"

Earlier today, June 11, Ronson wrote a message of thanks to his fans and explained that the bag and its contents were returned safely:

"thank you everyone, i got my bag back."
