Black Korg microKORG synth with yellow case sticker

I lost my black Korg microKORG synthesizer yesterday around 3pm. It was in a slim black hard case with a bright yellow 'backup' sticker on the case, and I think I left it near the cafe opposite The Forum on St Stephen's Street in Norwich, East Anglia. The synth is compact, 37 keys, matte black shell with an orange LED display that glows when powered. There's a small dent on the top-right corner and a worn circular logo patch on the back. It has sentimental value—it was a gift from my sister—and I really need it back for upcoming gigs this week.
