WINNIPEG - A Winnipeg man accused of abducting his young son and daughter and keeping them in Mexico for years is facing another charge.

On Wednesday, police charged Maryk with one count of criminal harassment.

Court documents allege Maryk tried to enlist a female family member to watch his ex-wife's Winnipeg home. Court documents say the woman did not carry out Maryk's alleged wishes.

Maryk, 41, is under a court order to have no contact with his ex-wife and two young children he is accused of abducting.

A police spokesman declined to comment on the new charge, saying it was the subject of a continuing investigation.

Maryk is in custody following his extradition from Mexico City last November. Maryk and his children went missing in 2008 while on a court-approved two week vacation.

Police tracked Maryk down last May when a tip from a neighbour led Mexican police to a heavily fortified home in the city of Guadalajara where the kids were found. Cops raided the home and arrested Maryk and co-accused Robert Groen.

Maryk is charged with two counts of abduction in contravention of a court order, and two counts of conspiracy to commit the indictable offence of abduction.

In November, police charged Maryk with an additional five sex-related offences involving a Winnipeg woman alleged to have occurred between January 2004 and May 2006. The charges include sexual assault, attempting to procure for the purposes of prostitution, and living off the avails of prostitution.
