Later that evening a male used her cards to clean out her bank accounts at an ATM machine in Clendon.
Higson said they were seeking the public's help in identifying the male.
"This was an absolutely appalling crime, and I am sure our community will be equally as shocked as we are by the absolute disregard these offenders had for this innocent elderly woman.
"She should feel safe in her own home, but was clearly targeted by these thugs, who preyed on her vulnerability."
Since the attack police had canvassed the area and located some CCTV footage.
