The witness,named Peter,told Fairfax Media he saw the pair sitting in a blue car in the McDonald's car park,and he noticed the woman trying to get out of the car and being restrained by the man.
"She got out and yelled something to the effect that he was trying to kill her,"Peter said.
"She came inside and he sat in the car for about 30 seconds to a minute. In that time one of the other guys who was near me was saying'Don't come out,don't get out of the car'.
