REM fans were warned today not to buy tickets on the black market for one of the band's hottest shows of the summer.
Gardai have launched an investigation after the alleged theft of 122 concert tickets for REM's sold-out gig in Dublin's Olympia Theatre.
The tickets went missing in transit between the UK and at the venue box office on Friday.
A spokesman for concert promoters MCD said: "While there has been no evidence to date that tickets have shown up on tout websites, REM today warned fans no to be misled into purchasing tickets at inflated prices from unofficial sources as they run the risk that these tickets could be stolen.
"All missing tickets have now been cancelled and deemed invalid by promoters thus holders will be refused entry on the night.''
Entitled Working Rehearsal, REM will play five-nights at the 1,600 capacity venue on June 30 and July 1, 3, 4, and 5.
The missing tickets are all standing tickets for Saturday June 30, and have the sequence numbers 0379 to 0500 inclusive. Strict security and Garda ticket checks will be in operation on the night.
REM begins work on their next record later this spring with producer Jacknife Lee who has produced records for U2, Snow Patrol, Bloc Party and Aqualung.
The five shows in Dublin will showcase songs from the forthcoming spring recording sessions with Lee, and, as such, will be a rare opportunity for the band to play new material for a live audience before the tracks appear on the band's 14th record.
"As tickets for this show were exclusively available from the website Sandbag and the Olympia box office only, anyone offered tickets for sale with the above sequence numbers should contact Gardai,'' added the spokesman.
