A couple were travelling on A205 in their car to their home address in south-east London and witnessed the kidnap.
As they approached Poynders Court the front seat passenger noticed what she described as a man and a woman standing on the pavement with the man behind the woman.
The man was wearing dark clothing. She started to watch more closely when she saw a handcuff. The woman on the pavement already had her left arm behind her back, and was in the process of "giving her other arm behind her back" as Couzens placed the handcuff on her right arm.
The Crown told the court that Sarah Everard was compliant, with her head down and did not appear to be arguing. The defendant appeared to be confident.
The immediate impression the passenger formed was that she was witnessing an undercover police officer arresting a woman, whom she assumed "must have done something wrong".
