Are British band Coldplay haunting their fans? Chris Martin and fellow group members have been forced to issue a statement making clear that two million light-up wristbands, given out to audiences on their recent tour, are not ‘mind control’ devices.

The pink-and-purple ‘Xylobands’ were designed to emit flashes of light in response to live performances of the band’s hits. They were never supposed to be more than souvenirs once they left the auditorium. Yet gig-goers reported being woken up at night by strange sightings. One alarmed fan wrote on the band’s website: ‘My Xyloband woke me in the night and it’s still glowing.’ A fan from Belgium fretted: ‘Mine is alive! It started flickering an hour ago.’

Clive Banks, of RB Concepts, which makes the bands, explained the ‘afterglow’ could have been caused by a nearby concert or a radio station frequency. Mr Banks reassured fans that the batteries will eventually run out. In the words of a popular Coldplay song, he simply advised ‘Don’t Panic’. - Daily Mail
