Further to middlesbrough's newspaper find:
Sunderland Daily Echo and Shipping Gazette 16 November 1880A CUNNING BOY
At the Borough Police Court yesterday, John Gooch, a young boy, was charged with stealing 10s 6d. From the evidence it appeared that on Saturday Morning an errand boy in the employ of Mr Robert Hodgson, draper, 151 High Street, was sent to a Mrs Blakie with some goods, prisoner being along with him.
Mrs Blakie not being in, he said he would call in the evening for the money and left the bill. In the afternoon prisoner called at the house and saw Mrs Blakie. He said he was the brother of the boy that had brought the goods, and he had been told to call for the money. He received 10s 6d, and receipted the bill. He was remanded for a week.
Presumably when he reappeared the next week, the magistrates decided that he should be sent to the Industrial school, but I can't find a report of that in the Sunderland paper
Sunderland Daily Echo and Shipping Gazette 20 June 1884TODAY'S POLICE INTELLIGENCE
Before Mr E Featherstonhaugh. Mr James Stokoe and Mr Robt. Thompson
A SUSPICIOUS CHARACTER
John Gooch was charged with frequenting the streets for an unlawful purpose. The prisoner, who is but a youth, was formerly in the Industrial School. He was loitering about a street, and when he saw P.C. Dykstra, he concealed himself.
Prisoner was committed for fourteen days.
The two reports appear to be about the same boy, possibly the one you are looking for.
I checked the image for the 1881 census for the Industrial School and the name looks to me like GOUCH (possibly a spelling error at the time), rather than CROUCH, he was listed as being 13. Given that in 1891 when he was back with his parents, his age was listed as 23, I would think its possible that its the right boy.
This page gives info about the Sunderland Industrial School in Silver Street:

http://www.twmuseums.org.uk/userfiles/UG14.pdf That is the TWAS list of court records they hold, long shot but you 'might' find something relevant in those, but it would involve a visit.
