The 45-year-old victim was walking home from work on a footpath beside Gresley Way at about 5.50pm on Tuesday February 10th.
As she headed towards Hartwell Way she passed by two men heading in the opposite direction.
A short while later she heard footsteps behind her and turned to see a man who knocked her to the ground and pinned her down with his forearm.
He wrestled the handbag from her grip before running off in the direction of Bretton Gate.
The victim suffered minor injuries and was left very upset and shaken.
The attacker is described as black, stocky, 5'9", possibly in his mid-20s and wearing a dark hooded coat and a dark scarf across the bottom half of his face
DC Kevin Poole, who is investigating, said: "This was a terrifying experience for the victim and I am keen to catch the person responsible as soon as possible.
"The area was very quiet at the time and the only other member of public the victim saw was a cyclist wearing a fluorescent jacket who rode past her onto the footpath and headed in the direction of Bretton Gate.
"I would urge that man or anyone else with information about this attack to come forward."
Anyone with information should contact DC Poole on 101, or Crimestoppers, anonymously, on 0800 555111.
