Devon and Cornwall's Police and Crime Commissioner has been interviewed over allegations relating to breaking election expenses rules.
Alison Hernandez faced calls to stand down from her role as PCC, soon after being elected in May last year.
She is under investigation by West Mercia police over allegations she failed to properly declare campaign expenses in the 2015 General Election.
Alison Hernandez was the Conservative Party's Election Agent for Torbay. The expenses forms that she signed, and the returns of three other Conservative Agents in Devon and Cornwall, are being investigated.
This investigation is one of a number of similar investigations being undertaken across the country.
