Replying to Shoplifting question

a friend of mine was caught shoplifting from a grocery store. he never left the store with the items before he was stopped. the manager took him into his office and took down his information. because he was compliant the manager didnt call the police but threatened to contact them and press charges if he doesnt come back and pay for the items he was going to steal (less than $10 worth) plus  $60 because the manager thought he had stolen from the store before. he said he looked like an experienced shoplifter because he didnt hesitate or look back and get nervous when heading towards the door.  When he took down his name he spelt it wrong but he still has his ss number and such. can he report the crime after 3 weeks? does my friend legally have to go back and pay? how would this hold up in court? im not trying to justify shoplifting. its a crime for a reason but wasnt the manager also in the wrong legally by not contacting the police and kind of blackmailing him? what do you think? any help is much apreciated.
