Another 23-year-old man of Montreal was charged with mischief by the Ottawa Police Service,[77] though he later claimed to have no memory of the event.[78] The incident, along with the common sight of persons skateboarding and riding bicycles on the memorial's podium, prompted the posting of sentries at the site,[79] though they are only present between 9 am and 5 pm from 9 April to 10 November.
