At least one attempted abduction publicized by the Edmonton police last month did not happen, investigators said Thursday.

On Nov. 30, a Grade 3 student from Lorelei Elementary School told police someone tried to kidnap her. When members of Edmonton's child protection unit interviewed her again, she recanted her story.

In a second case, on Nov. 23, a 9-year-old girl claimed that someone tried to grab her near 102nd Street and 114th Avenue but that she got away by kicking her attacker in the groin.

Detectives are still investigating those allegations but said they have concerns with the girl's version of events that place "the overall veracity of her story into question."

Police acknowledged Thursday that cases involving child witnesses pose special challenges to them.

On Nov. 15, a man kidnapped a six-year-old boy at knifepoint in Drumheller, Alta. Police found the boy unharmed several hours later. An 18-year-old man has been charged in the case.
