The trial of Toronto grocer David Chen, who was charged after making what he called a citizen's arrest on a convicted thief, is expected to wrap up Tuesday.

Chen and two co-workers were charged with assault and confinement after they allegedly chased down a thief and detained him in a van until police arrived.

Anthony Bennett stole $60 worth of plants from the Lucky Moose Food Mart on Dundas Street near Spadina Avenue in May 2009.

When he returned to the store about an hour later, he was allegedly chased by Chen, tied up and thrown into a van, prosecutors say.

Bennett admitted to stealing flowers to sell them on the street for $2 each. He was charged again Friday with five counts of theft on an unrelated matter.

Chen's case has raised questions on what constitutes a legal citizen's arrest and the rights of a shopkeeper.

The Crown argues that Chen's alleged actions took place too long after the original theft to be considered a legal citizen's arrest. Under the current law, an individual must catch someone in the act of committing a crime to make a citizen's arrest.
