Roger Spackman, 47, was arrested at a home address in Newtown for making pornographic photographs of children.
The Labour councillor had a 12-year career in Devon’s child protection services.
In 1998 he began working at Intervention Services for Devon County Council at a secure children’s home, occasionally working at other units. Before this, he was involved in the creation of Riverside Youth Café in Dawlish.
From September 2001 he worked full-time at a Secure Children’s Home until his role was axed in redundancies in February 2010.
Born in 1969, Spackman moved to Jamaica in 1972 before moving to Canada in 1974. After living in several Canadian towns and cities he returned to England in 1996.
He also chaired Exeter Labour Group between 2010 and 2014.
Cllr Spackman declined to comment when the allegations were put to him by a reporter.
