Police are trying to identify a man who allegedly groped a sleeping teenage girl on a transit bus last November in southwest Edmonton.

Edmonton police have laid hundreds of charges against 34 people, mainly teenager boys, believed to be responsible for dozens of violent robberies, thefts and attacks at places throughout the LRT system, at various recreation centres and malls in the city.

Police believe a group of teens are responsible for about 60 personal robberies, thefts and mischief calls at places throughout the LRT system and near recreation centres in north and south Edmonton.
