A Slovakian teenager burgled two South Yorkshire homes to try and feed his £100-a-day heroin habit, a court heard.
The 18-year-old was already subject to a deferred prison sentence after being convicted of burglary in Scotland in April.
Ondrej Tokar then moved to Rotherham and broke into houses at Bramwell Street and Hardwick Road, both in Eastwood.
Barrister Andrew Bailey, mitigating, told Sheffield Crown Court the teenager had only been in the United Kingdom for about seven months.
Mr Bailey said: “Since residing in this country he has developed a serious addiction to heroin and was taking in the region of £100 worth a day.”
In the first burglary at Bramwell Street in September, Tokar stole property worth thousands of pounds which has never been recovered.
He ransacked the house while the occupier was out and stole a camera, mobile phone, laptop computer, perfume and jewellery.
Susan Evans, prosecuting, said Tokar’s fingerprints were found on the inside of a front window which had been faulty.
Just before midnight on Tuesday, October 1, Tokar broke into a house on Hardwick Road while the occupier and her three children were asleep.
He took £80 in cash, but was spotted leaving through a window by a police officer.
Tokar gave a false name and address and was arrested.
Tokar, of no fixed address, admitted the two burglaries and was sentenced to 12 months in a young offenders’ institute.
Sentencing, Recorder Kate Tulk said: “Going into somebody else’s home to steal property is a serious matter.
“There is no evidence of any remorse on your part.”
