A youth worker who has been employed in Alberta and Saskatchewan has been charged with sex crimes involving a child.

Abraham Woo, 28, was arrested on Feb. 2 in Edmonton by the Alberta Law Enforcement Response Teams (ALERT) Internet Child Exploitation unit and charged with child luring, making child pornography, possession of child pornography, and distributing child pornography.

ALERT says Woo was involved in luring at least one child he knew through his youth work with Pasqua First Nation northeast of Regina, Sask.

Police say the offences took place over apps such as Snapchat and Facebook.

The incidents were initially reported to RCMP in Saskatchewan last month.

After seizing and examining several electronic devices from Woos home, police said they found photos that appear to have been taken in a locker room setting, leading investigators to believe there may be additional victims.

Police have released a censored version of the photo in hopes of identifying the location or victim.

Woo has worked with children at the following organizations in Alberta and Saskatchewan:

•  Pasqua First Nations Education: youth worker and education assistant;
•  Edmonton Bent Arrow Society: lodge keeper;
•  Shadow Dragon Youth Group Home: group home staff member;
•  Leduc Boys and Girls Club: youth programs coordinator; and
•  Pa Metawe Games: youth camps.

Several of the organizations released statements regarding Woo on Thursday.

Its important to note that [Woo] worked with us for a brief period of three months, five years ago. However, since his departure, he has not been associated with our organization in any capacity, Jenna Drover of Bent Arrow Traditional Healing Society said in an email to CTV News Edmonton.

At this time, we have no further comments on the matter. The safety and well-being of those we serve remains our utmost priority, and we support law enforcement authorities in their investigation.

Woo is known to have used the aliases Abraham Calling Bear Woo, Abraham Collingwood, and the Snapchat handle WolfBoy22, police say.

He has been released from custody and is scheduled to appear in court on Feb. 28.

Anyone with information or who believes they may be a victim is asked to call their local police department, or Crime Stoppers at 1-800-222-8477.
