Principal says man approached third school

Edmonton public school staff reviewed security procedures aftertwoalleged attacks in school washrooms.

In April 2006, a Grade 2 student at Oliver School was allegedly grabbed by a man hiding in a stall when she went to the washroom on her way out for recess.

Then in January, two Grade 3 girls told police they were in the bathroom at Victoria school when one of the girls was assaulted. Police believed the suspect entered the bathroom before the girls arrived.

Late that same afternoon, a 12-year-old girl on her way home from school was attacked in a downtown residential area.

Roma Paul, the principal at Coronation School, told CBC News that on that same Januaryday, a suspiciousman had come into her school.

"He was given information for the day care because that is what he'd requested. And he was with someone at all times, and he didn't have any contact withany students at all."

Paul contacted police with a description of the man.
