A 70-year-old accountant has been jailed for stealing £250,000 from a concrete testing specialist.
The assistant accountant amended digits on cheques before cashing them into her own account.
An investigation started when Lloyds TSB queried one of the 45 rogue cheques she had paid in.
The scam went undetected for six years, by which time she had banked £269,387.
The grandmother admitted spending the money on expensive holidays and weekends away with friends.
The pensioner who pleaded guilty to theft and fraud in Manchester received a three year jail sentence.
Passing sentence, Recorder Kevin Talbot told Rawlings: “It is, in my judgment, a fraud on a substantial scale, and the fraud that was committed was a serious breach of trust.
“The gravity of the offending behaviour, the breaches of trust month after month after month, and the amounts that were involved lead me to believe that the appropriate starting point [for a sentence] is a high one.”
A proceeds of crime hearing on July 30 will decide how much of the money she should pay back.
