Surrey Police told the Associated Press that Grills, 54, died late Monday in a London hospital after sustaining serious head injuries. Tour manager Paul McMullen was also killed.
Reports indicated that both men were trapped underneath a metal door after it fell on them at the loading bay of a venue in Guildford, 35 miles (55 kilometers) southwest of London, on Saturday.
"Sadly what we feared most has happened, Trevor lost the fight yesterday evening," the band said on its Facebook page earlier on Tuesday. "We would like to thank everybody for their good wishes and messages of support. We will miss him greatly and our thoughts go out to Leslie and the boys as well as to Paul McMullen's family at this very difficult time."
McMullen, 44, suffered serious leg injuries and died at the scene while paramedics treated him, multiple news reports said. The venue has since reopened, but the area where the tragedy occurred isn't being used and the Health and Safety Executive has been made aware of the incident."We are devastated to hear that Fisherman's Friends band member Trevor Grills died in hospital last night as a result of the head injuries suffered on Saturday," G Live's venue director Alvin Hargreaves, said, adding a police investigation is ongoing, and the venue is fully cooperating with them. "The thoughts and prayers of the G Live staff are with the families and friends of all who have been affected by this tragic accident."
Fisherman’s Friends signed a record deal with Universal Music in March 2010 after having performed in and around their native Cornwall, England since 1995.
Accolades for the group include a top 10 album and a performance at England’s prestigious Glastonbury Festival.
