The preliminary hearing of a Nova Scotia man at the centre of a case involving the confinement and sexual assault of a teenage boy has been delayed until the spring.

David James LeBlanc, 47, is accused of sexually assaulting and photographing young boys aged two and five.

His preliminary hearing is now set for May 16.

LeBlanc faces seven charges, including making child pornography.

He was arrested in Dec. 2010 after police seized computer equipment from an apartment in Dartmouth.

LeBlanc has also been charged in a separate, high-profile case in which a 16-year-old was allegedly chained and sexually assaulted inside a home in Upper Chelsea.

He faces charges of sexual assault causing bodily harm, uttering a death threat, administering a noxious substance with intent to cause bodily harm, kidnapping and breach of conditions in connection with the confinement case.
