BRAMPTON, Ont. -- An Ontario man who called himself "the Brampton Nanny" has been arrested in an investigation into alleged sexual assaults against children.

Peel region police say the 31-year-old man allegedly posted ads offering his services as a nanny and had been providing in-home child-care services for the past seven years.

Police say Kevin Cordeiro, of Brampton, Ont., was arrested last week and has been charged with two counts of sexual assault and two counts of sexual interference.

Investigators are concerned that there are more victims and are encouraging them to come forward.

Police say the force's Special Victims Unit is still investigating.
