 These were valid grounds for an arrest; the detention fit the definition of a proper arrest even though the police never called it one.The description of the incident as a detention, the police making it clear that he was in their custody by walking him into the house so he could put on different clothes, and Latimer's acceptance that the police were in control were enough for Latimer to understand he was being arrested.The Court then turned to whether the police's decision not to tell Mr. Latimer he was being arrested and could face a murder charge breached section 10(a) of the "Charter".
