Police are now probing two alleged indecent assaults on two girls, and a serious sexual assault on a boy aged under 10, in Lancashire by the late Jimmy Savile.
All date back to 1961.
The news came after a damning report, by Scotland Yard and the NSPCC, was released.
Four other people who live in Lancashire have made allegations that he attacked them, but not while they lived in the county.
A Lancashire Police spokesman said: “There are three offences in Lancashire which we are investigating in close liaison with the Met. They all occurred in 1961.
“The four offences we referred to previously were not committed in Lancashire, although the victims now reside here and they reported those offences to us. These were reported to Operation Yewtree and passed to the relevant forces.”
