CALGARY -- The former courthouse security guard who is facing dozens of child-sex-related allegations is back behind bars on similar new charges.

Daniel Thomas Mackie, 25, is is accused of trying to lure a minor on the Internet and charged with invitation to sexual touching involving a teenage boy.

He is also charged with two counts of breaching the conditions of his previous release, which bar him from using the Internet and having contact with a minor.

Mackie was arrested in February and charged with 77 offences, including making, possessing, accessing and distributing child pornography, child luring, invitation to sexual touching, extortion and impersonation.

None of the allegations involve actual physical contact with children.

Mackie was arrested a second time in April and charged with a single weapons offence.

The February charges followed an investigation which began a year ago after police received separate complaints from administrators of a social networking site and concerned parents.

The investigation identified more than a dozen male and female alleged victims around Alberta between the ages of 11 and 16 dating back to 2009.

Mackie was supposed to face a bail hearing Tuesday, but his lawyer, James Wyman, asked that it be postponed.

Wyman told provincial court Judge Sean Dunnigan he is working on lining up a surety, which he hopes can be used to win Mackie's freedom once again.

Crown prosecutor Nadine Nesbitt will be seeking Mackie's detention on the new charges and will ask that his bail on the earlier allegations be revoked.

Mackie returns to court Monday.
