A vicious gang of three knocked a 33-year-old woman to the floor and kicked her so hard that her nose and cheekbone were fractured.
The unprovoked attack happened in broad daylight on Sunday afternoon.
The victim was walking home along the footpath off Cranborne Avenue, Westcroft, which runs between Sissinghurst Drive and Brantwood Close, between about 2pm and 2.30pm.
She was struck on the head from behind, causing her to fall to the floor.
While on the floor she was kicked, causing her to sustain a broken nose, fractured cheekbone, fractured eye socket and bruising to her hands, ribs, feet and back.
She is currently being treated at Milton Keynes General Hospital.
Police are treating the attack as grievous bodily harm and say the victim believes there were three offenders involved.
None of her belongings was taken during the offence.
