British thrash metaller Onslaught have been forced to cancel the remaining dates on their UK tour due to dramatic medical problems with frontman Sy Keeler. The singer was rushed to hospital before the band's show at Leeds Rios suffering from acute loss of vision, which doctors recognise as a detached retina and operated upon immediately.

The band are hoping to reschedule the rest of the tour to later this year and thank the fans for their continued support.
