WWE Diva Emma is a real life heel ... arrested for stealing an iPad case from a Walmart.
Emma was busted in Hartford Monday night after Walmart security spotted her swiping a red iHome 'Slim Swivel' iPad Mini case ... on sale for $21.14.
Cops tell TMZ ... Emma was charged with misdemeanor larceny in the 6th degree ... who knew there were that many degrees?
The legal system in Hartford is lightning quick -- she's already been to court and was sentenced to one day of community service.
WWE RAW was at the XL Center in Hartford as the crime went down.
Emma's lawyer chalks it up to an innocent mistake, saying she just forgot to pay while trying to navigate the self-checkout machine.
