A further allegation of postal vote fraud in the Leicestershire police and crime commissioner election has been made.
Police were already investigating UKIP claims that a number of postal ballots returned in Leicester had signatures which did not match the control samples provided to city council officers.
UKIP says it observed the discrepancies at a verification session before Thursday's election.
The police have launched Operation Horoscope to look into the complaint and now Andy McWilliam, agent to defeated UKIP candidate David Sprason, said he had reported concerns about postal votes in Charnwood.
Mr McWilliam said six out of 17 Charnwood postal ballots seen by UKIP did not have a matching signatures.
