British post-punk group Killing Joke's frontman Jaz Coleman is reportedly missing, according to a message the group posted on Facebook.
The band says Coleman disappeared after "maligning both the Cult and the Mission" on Facebook. Killing Joke was to have toured with both bands in September.
"He is now AWOL and has not contacted any of his band mates," the post continues. "We are deeply embarrassed by this and offer our sincere apologies to all involved. We are all concerned about our missing singer's welfare."
The rest of the band promised that they would do their best to play the tour, though they added, "If this proves not possible, Killing Joke will make alternative arrangements to compensate for the trouble caused."
The note concluded, "Meanwhile we are doing everything we can to make this tour happen and locate our missing singer."
