An investigation has been launched after Telford & Wrekin Council admitted sending out more than 200 letters disclosing personal information about other residents . Telford & Wrekin Council 33 Comments The error , which saw 222 incorrectly printed letters sent to homes in the borough , was in breach of data rules , the authority has admitted . Council chiefs today apologised for the blunder , which they said was down to human error . A disabled woman in her 60s , who lives in Telford but does not want to be named , said someone else 's name , address and account number had been printed on a form she received from the authority to apply for a council tax reduction . She said : " I 'm disabled and every year I get a form to apply for a reduction on my council tax . " When I had my letter this year it had someone else 's name , address and account number on the form . " I do n't know if my details have gone to someone else either . " I phoned them up and they said there had been a serious error and they were investigating what had happened . " That 's how I found out it was n't just me . " They tell you that your details are going to be safe but then something like this happens . " I think it 's disgusting . " Russell Griffin , spokesman for Telford & Wrekin Council , said letters of apology had already been sent out to residents and a full investigation was under way . He added : " We can confirm that a data breach has occurred with 222 customer letters being incorrectly printed as double- sided rather than single - sided . " Each letter should have had a blank reverse but the next customer 's details were printed instead . We would like to apologise to our customers for this breach , which was caused by human error . " We are carrying out a full investigation to establish how this happened and will be reviewing our procedures to see what changes we can make to ensure this does not happen again . A letter of explanation complete with our sincere apologies has gone out to all those affected . " ;
