"We are shocked and filled with overwhelming sadness with the untimely passing of our dear friend, family member and bandmate Andy 'Fletch' Fletcher. Fletch had a true heart of gold and was always there when you needed support, a lively conversation, a good laugh, or a cold pint," they wrote. Fletcher's cause of death has not been revealed. The British electronic band was founded by Fletcher, Dave Gahan, Martin Gore and Vince Clarke in 1980. Fletcher was the keyboard player for the group and was with the band for over 40 years.
