Police believe a music teacher who sexually abused four girls also attacked other females.
Detectives think that there are more victims attacked by 46-year-old Christopher Dunn, who was jailed last week for abusing a teenage girl more than 10 years ago.
Christopher Dunn, of Pulford Drive, Thurnby, who was jailed for six years in 2014 for sexual offences involving three other girls, was brought back to court when a fourth victim made a complaint about him.
The girl said she felt unable to come forward when Dunn was on trial for the offences involving the other girls – all committed at around the same time – Leicester Crown Court was told.
Detective Constable Jamie Carr, the investigating officer, believes there may be other victims of Dunn who have not yet come forward.
