 A university graduate described as a “respectable and intelligent” woman is seeking professional(专业的) help after being convicted of (证明有……罪)shoplifting for the second time in six months.

Ana Luz, recently studying for her PhD, has been told she could end up behind bars unless she can control the desire to steal from shops .

Luz ,who lives with her partner in Fitzwilliam Road ,Cambridge ,admitted stealing clothes worth £9.95 from John Lewis in Oxford Street ,London ,on March 9.

Phillip Lemoyne ,prosecuting(起诉),said Luz selected some clothes from a display and took them to the ladies’ toilet in the store .When she came out again she was wearing one of the skirts she had selected ,having taken off the anti-theft security alarms(防盗警报装置).

She was stopped and caught after leaving the store without paying, Mr Lemoyne said.

He added that she was upset on her arrest and apologized for her actions.

Luz,28, was said to have been convicted of shoplifting by Cambridge judges last October ,but Morag Duff, defending ,said she had never been in trouble with the police before that .

“She is ashamed and embarrassed(尴尬) but doesn’t really have any explanation why she did this ,” Miss Duff said . “She didn’t intend to steal when she went into the store .She is at a loss to explain it. She is otherwise a very respectable and intelligent young lady .She went to her doctor and asked for advice because she wants to know if there is anything in particular that caused her to do this.”

Judge David Azan fined Luz £ 50,  and warned : “You’ve got a criminal record .If you carry on like this ,you will end up in prison ,which will ruin your bright future you may have.”

Luz achieved a degree in design at university in her native Spain, went on to a famous university in Berlin , Germany for her master’s degree and is now studying for a PhD at Cambridge University ,UK.
