Police have reissued an appeal for witnesses after a mother was knocked unconscious and raped in front of her three-year-old son.
The 23-year-old was attacked by a man known as Derek, after meeting him several times following an online introduction.
On the morning of September 30, the woman met her attacker on the M2 and he followed her to her flat near Sutton town centre.
He then punched her in the face, knocking her unconscious, and raped her.
A police spokesman said the man was white, in his late 40s of muscular build and drove an old green Land Rover with a canvas roof and a spare wheel with an eagle design cover.
