A 59-year-old man was arrested yesterday in connection with a series of sexual assaults in the early 1980s.
The man, who was detained in the Melton area, was being questioned by detectives last night about four incidents in Syston in 1983 and 1984.
Police said four victims' complaints had been investigated at the time, but had remained unsolved. Those incidents have since been linked to a number of other crimes in the area in the same period.
It is understood the arrest is not linked to Operation Yew Tree, the Metropolitan Police investigation into historical allegations of sexual assault against former BBC personality Jimmy Savile and a number of other men.
A Leicestershire Police spokesman said the arrest followed a review into Syston "cold cases".
The force urged victims who have never reported crimes committed against them to come forward, no matter how much time has passed.
The spokesman said: "We would like to reassure anyone who is a victim of any offence – historically or presently – to come forward at any time and we will promise to handle your investigation professionally and sensitively."
Contact Leicestershire Police on 101.
