Essex Police is to carry out a review of historic allegations of sex abuse against young boys in local authority and foster care.
A number of prosecutions were brought at the time and two people were convicted.
But, there are now concerns the investigations in the 80s and 90s weren’t thorough enough.
Chief Constable Stephen Kavanagh said: “At present we have allegations but no victims, suspects or locations.
“If you have information about such crimes or are yourself a victim or survivor of sexual abuse as a child during this period, I need you to come forward and contact us directly on 101, asking to speak to a specialist officer within our Child Abuse Investigation teams.”
